"\n"} else {print "It didn't work!->" . $response->code . "\n"} =head1 DESCRIPTION L<LWP::Authen::Ntlm> allows LWP to authenticate against servers that are using the NTLM authentication scheme popularized by Microsoft. This type of authentication is common on intranets of Microsoft-centric organizations. The module takes advantage of the Authen::NTLM module by Mark Bush. Since there is also another Authen::NTLM module available from CPAN by Yee Man Chan with an entirely different interface, it is necessary to ensure that you have the correct NTLM module. In addition, there have been problems with incompatibilities between different versions of L<Mime::Base64>, which Bush's L<Authen::NTLM> makes use of. Therefore, it is necessary to ensure that your Mime::Base64 module supports exporting of the C<encode_base64> and C<decode_base64> functions. =head1 USAGE The module is used indirectly through LWP, rather than including it directly in your code. The LWP system will invoke the NTLM authentication when it encounters the authentication scheme while attempting to retrieve a URL from a server. In order for the NTLM authentication to work, you must have a few things set up in your code prior to attempting to retrieve the URL: =over 4 =item * Enable persistent HTTP connections To do this, pass the C<< "keep_alive=>1" >> option to the L<LWP::UserAgent> when creating it, like this: my $ua = LWP::UserAgent->new(keep_alive=>1); =item * Set the credentials on the UserAgent object The credentials must be set like this: $ua->credentials('www.company.com:80', '', "MyDomain\\MyUserCode", 'MyPassword'); Note that you cannot use the L<HTTP::Request> object's C<authorization_basic()> method to set the credentials. Note, too, that the C<'www.company.com:80'> portion only sets credentials on the specified port AND it is case-sensitive (this is due to the way LWP is coded, and has nothing to do with LWP::Authen::Ntlm) =back =head1 AVAILABILITY General queries regarding LWP should be made to the LWP Mailing List.

The mapping from file extensions to media types is defined by the F<media.types> file. If the F<~/.media.types> file exists it is used instead. For backwards compatibility we will also look for F<~/.mime.types>. The following functions are exported by default: =over 4 =item guess_media_type( $filename ) =item guess_media_type( $uri ) =item guess_media_type( $filename_or_object, $header_to_modify ) This function tries to guess media type and encoding for a file or objects that support the a C<path> or C<filename> method, eg, L<URI> or L<File::Temp> objects. When an object does not support either method, it will be stringified to determine the filename. It returns the content type, which is a string like C<"text/html">. In array context it also returns any content encodings applied (in the order used to encode the file). You can pass a URI object reference, instead of the file name. If the type can not be deduced from looking at the file name, then guess_media_type() will let the C<-T> Perl operator take a look. If this works (and C<-T> returns a TRUE value) then we return I<text/plain> as the type, otherwise we return I<application/octet-stream> as the type. The optional second argument should be a reference to a HTTP::Headers object or any object that implements the $obj->header method in a similar way. When it is present the values of the 'Content-Type' and 'Content-Encoding' will be set for this header. =item media_suffix( $type, ... ) This function will return all suffixes that can be used to denote the specified media type(s). Wildcard types can be used. In a scalar context it will return the first suffix found. Examples: @suffixes = media_suffix('image/*', 'audio/basic'); $suffix = media_suffix('text/html'); =back The following functions are only exported by explicit request: =over 4 =item add_type( $type, @exts ) Associate a list of file extensions with the given media type. Example: add_type("x-world/x-vrml" => qw(wrl vrml)); =item add_encoding( $type, @ext ) Associate a list of file extensions with an encoding type. Example: add_encoding("x-gzip" => "gz"); =item read_media_types( @files ) Parse media types files and add the type mappings found there.

Details of its interface is likely to change in the future. =head1 SYNOPSIS use LWP::ConnCache; my $cache = LWP::ConnCache->new; $cache->deposit($type, $key, $sock); $sock = $cache->withdraw($type, $key); =head1 DESCRIPTION The C<LWP::ConnCache> class is the standard connection cache manager for L<LWP::UserAgent>. =head1 METHODS The following basic methods are provided: =head2 new my $cache = LWP::ConnCache->new( %options ) This method constructs a new L<LWP::ConnCache> object. The only option currently accepted is C<total_capacity>. If specified it initializes the L<LWP::ConnCache/total_capacity> option. It defaults to C<1>. =head2 total_capacity my $cap = $cache->total_capacity; $cache->total_capacity(0); # drop all immediately $cache->total_capacity(undef); # no limit $cache->total_capacity($number); Get/sets the number of connection that will be cached. Connections will start to be dropped when this limit is reached. If set to C<0>, then all connections are immediately dropped. If set to C<undef>, then there is no limit. =head2 capacity my $http_capacity = $cache->capacity('http'); $cache->capacity('http', 2 ); Get/set a limit for the number of connections of the specified type that can be cached. The first parameter is a short string like C<"http"> or C<"ftp">. =head2 drop $cache->drop(); # Drop ALL connections # which is just a synonym for: $cache->drop(sub{1}); # Drop ALL connections # drop all connections older than 22 seconds and add a reason for it! $cache->drop(22, "Older than 22 secs dropped"); # which is just a synonym for: $cache->drop(sub { my ($conn, $type, $key, $deposit_time) = @_; if ($deposit_time < 22) { # true values drop the connection return 1; } # false values don't drop the connection return 0; }, "Older than 22 secs dropped" ); Drop connections by some criteria. The $checker argument is a subroutine that is called for each connection. If the routine returns a TRUE value then the connection is dropped. The routine is called with C<($conn, $type, $key, $deposit_time)> as arguments. Shortcuts: If the C<$checker> argument is absent (or C<undef>) all cached connections are dropped. If the $checker is a number then all connections untouched that the given number of seconds or more are dropped. If $checker is a string then all connections of the given type are dropped. The C<reason> is passed on to the L<LWP::ConnCache/dropped> method. =head2 prune $cache->prune(); Calling this method will drop all connections that are dead. This is tested by calling the L<LWP::ConnCache/ping> method on the connections. If the L<LWP::ConnCache/ping> method exists and returns a false value, then the connection is dropped. =head2 get_types my @types = $cache->get_types(); This returns all the C<type> fields used for the currently cached connections. =head2 get_connections my @conns = $cache->get_connections(); # all connections my @conns = $cache->get_connections('http'); # connections for http This returns all connection objects of the specified type. If no type is specified then all connections are returned. In scalar context the number of cached connections of the specified type is returned. =head1 PROTOCOL METHODS The following methods are called by low-level protocol modules to try to save away connections and to get them back. =head2 deposit $cache->deposit($type, $key, $conn); This method adds a new connection to the cache. As a result, other already cached connections might be dropped. Multiple connections with the same type/key might be added. =head2 withdraw my $conn = $cache->withdraw($type, $key); This method tries to fetch back a connection that was previously deposited. If no cached connection with the specified $type/$key is found, then C<undef> is returned. There is not guarantee that a deposited connection can be withdrawn, as the cache manger is free to drop connections at any time. =head1 INTERNAL METHODS The following methods are called internally. Subclasses might want to override them. =head2 enforce_limits $conn->enforce_limits([$type]) This method is called with after a new connection is added (deposited) in the cache or capacity limits are adjusted. The default implementation drops connections until the specified capacity limits are not exceeded. =head2 dropping $conn->dropping($conn_record, $reason) This method is called when a connection is dropped. The record belonging to the dropped connection is passed as the first argument and a string describing the reason for the drop is passed as the second argument. The default implementation makes some noise if the C<$LWP::ConnCache::DEBUG> variable is set and nothing more. =head1 SUBCLASSING For specialized cache policy it makes sense to subclass C<LWP::ConnCache> and perhaps override the L<LWP::ConnCache/deposit>, L<LWP::ConnCache/enforce_limits>, and L<LWP::ConnCache/dropping> methods. The object itself is a hash. Keys prefixed with C<cc_> are reserved for the base class. =head1 SEE ALSO L<LWP::UserAgent> =head1 COPYRIGHT Copyright 2001 Gisle Aas.

If you need more control or access to the header fields in the requests sent and responses received, then you should use the full object-oriented interface provided by the L<LWP::UserAgent> module. The module will also export the L<LWP::UserAgent> object as C<$ua> if you ask for it explicitly. The user agent created by this module will identify itself as C<LWP::Simple/#.##> and will initialize its proxy defaults from the environment (by calling C<< $ua->env_proxy >>). =head1 FUNCTIONS The following functions are provided (and exported) by this module: =head2 get my $res = get($url); The get() function will fetch the document identified by the given URL and return it. It returns C<undef> if it fails. The C<$url> argument can be either a string or a reference to a L<URI> object. You will not be able to examine the response code or response headers (like C<Content-Type>) when you are accessing the web using this function. If you need that information you should use the full OO interface (see L<LWP::UserAgent>). =head2 head my $res = head($url); Get document headers. Returns the following 5 values if successful: ($content_type, $document_length, $modified_time, $expires, $server) Returns an empty list if it fails. In scalar context returns TRUE if successful. =head2 getprint my $code = getprint($url); Get and print a document identified by a URL. The document is printed to the selected default filehandle for output (normally STDOUT) as data is received from the network. If the request fails, then the status code and message are printed on STDERR. The return value is the HTTP response code. =head2 getstore my $code = getstore($url, $file) Gets a document identified by a URL and stores it in the file. The return value is the HTTP response code. =head2 mirror my $code = mirror($url, $file); Get and store a document identified by a URL, using I<If-modified-since>, and checking the I<Content-Length>. Returns the HTTP response code. =head1 STATUS CONSTANTS This module also exports the L<HTTP::Status> constants and procedures. You can use them when you check the response code from L<LWP::Simple/getprint>, L<LWP::Simple/getstore> or L<LWP::Simple/mirror>. The constants are: RC_CONTINUE RC_SWITCHING_PROTOCOLS RC_OK RC_CREATED RC_ACCEPTED RC_NON_AUTHORITATIVE_INFORMATION RC_NO_CONTENT RC_RESET_CONTENT RC_PARTIAL_CONTENT RC_MULTIPLE_CHOICES RC_MOVED_PERMANENTLY RC_MOVED_TEMPORARILY RC_SEE_OTHER RC_NOT_MODIFIED RC_USE_PROXY RC_BAD_REQUEST RC_UNAUTHORIZED RC_PAYMENT_REQUIRED RC_FORBIDDEN RC_NOT_FOUND RC_METHOD_NOT_ALLOWED RC_NOT_ACCEPTABLE RC_PROXY_AUTHENTICATION_REQUIRED RC_REQUEST_TIMEOUT RC_CONFLICT RC_GONE RC_LENGTH_REQUIRED RC_PRECONDITION_FAILED RC_REQUEST_ENTITY_TOO_LARGE RC_REQUEST_URI_TOO_LARGE RC_UNSUPPORTED_MEDIA_TYPE RC_INTERNAL_SERVER_ERROR RC_NOT_IMPLEMENTED RC_BAD_GATEWAY RC_SERVICE_UNAVAILABLE RC_GATEWAY_TIMEOUT RC_HTTP_VERSION_NOT_SUPPORTED =head1 CLASSIFICATION FUNCTIONS The L<HTTP::Status> classification functions are: =head2 is_success my $bool = is_success($rc); True if response code indicated a successful request. =head2 is_error my $bool = is_error($rc) True if response code indicated that an error occurred. =head1 CAVEAT Note that if you are using both LWP::Simple and the very popular L<CGI> module, you may be importing a C<head> function from each module, producing a warning like C<Prototype mismatch: sub main::head ($) vs none>. Get around this problem by just not importing LWP::Simple's C<head> function, like so: use LWP::Simple qw(!head); use CGI qw(:standard); # then only CGI.pm defines a head() Then if you do need LWP::Simple's C<head> function, you can just call it as C<LWP::Simple::head($url)>. =head1 SEE ALSO L<LWP>, L<lwpcook>, L<LWP::UserAgent>, L<HTTP::Status>, L<lwp-request>, L<lwp-mirror> =cut PK ! ���j?# ?# Protocol.pmnu �[��� package LWP::Protocol; use parent 'LWP::MemberMixin'; our $VERSION = '6.61'; use strict; use Carp (); use HTTP::Status (); use HTTP::Response (); use Try::Tiny qw(try catch); my %ImplementedBy = (); # scheme => classname sub new { my($class, $scheme, $ua) = @_; my $self = bless { scheme => $scheme, ua => $ua, # historical/redundant max_size => $ua->{max_size}, }, $class; $self; } sub create { my($scheme, $ua) = @_; my $impclass = LWP::Protocol::implementor($scheme) or Carp::croak("Protocol scheme '$scheme' is not supported"); # hand-off to scheme specific implementation sub-class my $protocol = $impclass->new($scheme, $ua); return $protocol; } sub implementor { my($scheme, $impclass) = @_; if ($impclass) { $ImplementedBy{$scheme} = $impclass; } my $ic = $ImplementedBy{$scheme}; return $ic if $ic; return '' unless $scheme =~ /^([.+\-\w]+)$/; # check valid URL schemes $scheme = $1; # untaint $scheme =~ tr/.+-/_/; # make it a legal module name # scheme not yet known, look for a 'use'd implementation $ic = "LWP::Protocol::$scheme"; # default location $ic = "LWP::Protocol::nntp" if $scheme eq 'news'; #XXX ugly hack no strict 'refs'; # check we actually have one for the scheme: unless (@{"${ic}::ISA"}) { # try to autoload it try { (my $class = $ic) =~ s{::}{/}g; $class .= '.pm' unless $class =~ /\.pm$/; require $class; } catch { my $error = $_; if ($error =~ /Can't locate/) { $ic = ''; } else { die "$error\n"; } }; } $ImplementedBy{$scheme} = $ic if $ic; $ic; } sub request { my($self, $request, $proxy, $arg, $size, $timeout) = @_; Carp::croak('LWP::Protocol::request() needs to be overridden in subclasses'); } # legacy sub timeout { shift->_elem('timeout', @_); } sub max_size { shift->_elem('max_size', @_); } sub collect { my ($self, $arg, $response, $collector) = @_; my $content; my($ua, $max_size) = @{$self}{qw(ua max_size)}; # This can't be moved to Try::Tiny due to the closures within causing # leaks on any version of Perl prior to 5.18. # https://perl5.git.perl.org/perl.git/commitdiff/a0d2bbd5c my $error = do { #catch local $@; local $\; # protect the print below from surprises eval { # try if (!defined($arg) || !$response->is_success) { $response->{default_add_content} = 1; } elsif (!ref($arg) && length($arg)) { open(my $fh, ">", $arg) or die "Can't write to '$arg': $!"; binmode($fh); push(@{$response->{handlers}{response_data}}, { callback => sub { print $fh $_[3] or die "Can't write to '$arg': $!"; 1; }, }); push(@{$response->{handlers}{response_done}}, { callback => sub { close($fh) or die "Can't write to '$arg': $!"; undef($fh); }, }); } elsif (ref($arg) eq 'CODE') { push(@{$response->{handlers}{response_data}}, { callback => sub { &$arg($_[3], $_[0], $self); 1; }, }); } else { die "Unexpected collect argument '$arg'"; } $ua->run_handlers("response_header", $response); if (delete $response->{default_add_content}) { push(@{$response->{handlers}{response_data}}, { callback => sub { $_[0]->add_content($_[3]); 1; }, }); } my $content_size = 0; my $length = $response->content_length; my %skip_h; while ($content = &$collector, length $$content) { for my $h ($ua->handlers("response_data", $response)) { next if $skip_h{$h}; unless ($h->{callback}->($response, $ua, $h, $$content)) { # XXX remove from $response->{handlers}{response_data} if present $skip_h{$h}++; } } $content_size += length($$content); $ua->progress(($length ?

When creating an instance of this class using C<LWP::Protocol::create($url)>, and you get an initialized subclass appropriate for that access method. In other words, the L<LWP::Protocol/create> function calls the constructor for one of its subclasses. All derived C<LWP::Protocol> classes need to override the C<request()> method which is used to service a request. The overridden method can make use of the C<collect()> method to collect together chunks of data as it is received. =head1 METHODS The following methods and functions are provided: =head2 new my $prot = LWP::Protocol->new(); The LWP::Protocol constructor is inherited by subclasses. As this is a virtual base class this method should B<not> be called directly. =head2 create my $prot = LWP::Protocol::create($scheme) Create an object of the class implementing the protocol to handle the given scheme. This is a function, not a method. It is more an object factory than a constructor. This is the function user agents should use to access protocols. =head2 implementor my $class = LWP::Protocol::implementor($scheme, [$class]) Get and/or set implementor class for a scheme. Returns C<''> if the specified scheme is not supported. =head2 request $response = $protocol->request($request, $proxy, undef); $response = $protocol->request($request, $proxy, '/tmp/sss'); $response = $protocol->request($request, $proxy, \&callback, 1024); Dispatches a request over the protocol, and returns a response object. This method needs to be overridden in subclasses. Refer to L<LWP::UserAgent> for description of the arguments. =head2 collect my $res = $prot->collect(undef, $response, $collector); # stored in $response my $res = $prot->collect($filename, $response, $collector); my $res = $prot->collect(sub { ... }, $response, $collector); Collect the content of a request, and process it appropriately into a scalar, file, or by calling a callback. If the first parameter is undefined, then the content is stored within the C<$response>. If it's a simple scalar, then it's interpreted as a file name and the content is written to this file. If it's a code reference, then content is passed to this routine. The collector is a routine that will be called and which is responsible for returning pieces (as ref to scalar) of the content to process. The C<$collector> signals C<EOF> by returning a reference to an empty string. The return value is the L<HTTP::Response> object reference. B<Note:> We will only use the callback or file argument if C<< $response->is_success() >>. This avoids sending content data for redirects and authentication responses to the callback which would be confusing. =head2 collect_once $prot->collect_once($arg, $response, $content) Can be called when the whole response content is available as content. This will invoke L<LWP::Protocol/collect> with a collector callback that returns a reference to C<$content> the first time and an empty string the next. =head1 SEE ALSO Inspect the F<LWP/Protocol/file.pm> and F<LWP/Protocol/http.pm> files for examples of usage. =head1 COPYRIGHT Copyright 1995-2001 Gisle Aas.

Robots should be nice to the servers they visit. They should consult the F</robots.txt> file to ensure that they are welcomed and they should not make requests too frequently. But before you consider writing a robot, take a look at L<http://www.robotstxt.org/>. When you use an I<LWP::RobotUA> object as your user agent, then you do not really have to think about these things yourself; C<robots.txt> files are automatically consulted and obeyed, the server isn't queried too rapidly, and so on. Just send requests as you do when you are using a normal I<LWP::UserAgent> object (using C<< $ua->get(...) >>, C<< $ua->head(...) >>, C<< $ua->request(...) >>, etc.), and this special agent will make sure you are nice. =head1 METHODS The LWP::RobotUA is a sub-class of L<LWP::UserAgent> and implements the same methods. In addition the following methods are provided: =head2 new my $ua = LWP::RobotUA->new( %options ) my $ua = LWP::RobotUA->new( $agent, $from ) my $ua = LWP::RobotUA->new( $agent, $from, $rules ) The LWP::UserAgent options C<agent> and C<from> are mandatory. The options C<delay>, C<use_sleep> and C<rules> initialize attributes private to the RobotUA. If C<rules> are not provided, then L<WWW::RobotRules> is instantiated providing an internal database of F<robots.txt>. It is also possible to just pass the value of C<agent>, C<from> and optionally C<rules> as plain positional arguments. =head2 delay my $delay = $ua->delay; $ua->delay( $minutes ); Get/set the minimum delay between requests to the same server, in I<minutes>. The default is C<1> minute. Note that this number doesn't have to be an integer; for example, this sets the delay to C<10> seconds: $ua->delay(10/60); =head2 use_sleep my $bool = $ua->use_sleep; $ua->use_sleep( $boolean ); Get/set a value indicating whether the UA should L<LWP::RobotUA/sleep> if requests arrive too fast, defined as C<< $ua->delay >> minutes not passed since last request to the given server. The default is true. If this value is false then an internal C<SERVICE_UNAVAILABLE> response will be generated. It will have a C<Retry-After> header that indicates when it is OK to send another request to this server. =head2 rules my $rules = $ua->rules; $ua->rules( $rules ); Set/get which I<WWW::RobotRules> object to use. =head2 no_visits my $num = $ua->no_visits( $netloc ) Returns the number of documents fetched from this server host. Yeah I know, this method should probably have been named C<num_visits> or something like that. :-( =head2 host_wait my $num = $ua->host_wait( $netloc ) Returns the number of I<seconds> (from now) you must wait before you can make a new request to this host. =head2 as_string my $string = $ua->as_string; Returns a string that describes the state of the UA. Mainly useful for debugging. =head1 SEE ALSO L<LWP::UserAgent>, L<WWW::RobotRules> =head1 COPYRIGHT Copyright 1996-2004 Gisle Aas.

Please see L<LWP::ConsoleLogger> for your debugging needs. LWP::Debug is used to provide tracing facilities, but these are not used by LWP any more. The code in this module is kept around (undocumented) so that 3rd party code that happens to use the old interfaces continue to run. One useful feature that LWP::Debug provided (in an imprecise and troublesome way) was network traffic monitoring. The following section provides some hints about recommended replacements. =head2 Network traffic monitoring The best way to monitor the network traffic that LWP generates is to use an external TCP monitoring program. The L<WireShark|http://www.wireshark.org/> program is highly recommended for this. Another approach it to use a debugging HTTP proxy server and make LWP direct all its traffic via this one. Call C<< $ua->proxy >> to set it up and then just use LWP as before. For less precise monitoring needs just setting up a few simple handlers might do. The following example sets up handlers to dump the request and response objects that pass through LWP: use LWP::UserAgent; $ua = LWP::UserAgent->new; $ua->default_header('Accept-Encoding' => scalar HTTP::Message::decodable()); $ua->add_handler("request_send", sub { shift->dump; return }); $ua->add_handler("response_done", sub { shift->dump; return }); $ua->get("http://www.example.com"); =head1 SEE ALSO L<LWP::ConsoleLogger>, L<LWP::ConsoleLogger::Everywhere>, L<LWP::UserAgent> =cut PK ! �; C C DebugFile.pmnu �[��� package LWP::DebugFile; our $VERSION = '6.61'; # legacy stub 1; PK ! �}FS S Protocol/cpan.pmnu �[��� package LWP::Protocol::cpan; use strict; use parent qw(LWP::Protocol); our $VERSION = '6.61'; require URI; require HTTP::Status; require HTTP::Response; our $CPAN; unless ($CPAN) { # Try to find local CPAN mirror via $CPAN::Config eval { require CPAN::Config; if($CPAN::Config) { my $urls = $CPAN::Config->{urllist}; if (ref($urls) eq "ARRAY") { my $file; for (@$urls) { if (/^file:/) { $file = $_; last; } } if ($file) { $CPAN = $file; } else { $CPAN = $urls->[0]; } } } }; $CPAN ||= "http://cpan.org/"; # last resort } # ensure that we don't chop of last part $CPAN .= "/" unless $CPAN =~ m,/$,; sub request { my($self, $request, $proxy, $arg, $size) = @_; # check proxy if (defined $proxy) { return HTTP::Response->new(HTTP::Status::RC_BAD_REQUEST, 'You can not proxy with cpan'); } # check method my $method = $request->method; unless ($method eq 'GET' || $method eq 'HEAD') { return HTTP::Response->new(HTTP::Status::RC_BAD_REQUEST, 'Library does not allow method ' .

This module is a plug-in to the LWP protocol handling, so you don't use it directly. Once the module is installed LWP is able to access sites using HTTP over SSL/TLS. If hostname verification is requested by LWP::UserAgent's C<ssl_opts>, and neither C<SSL_ca_file> nor C<SSL_ca_path> is set, then C<SSL_ca_file> is implied to be the one provided by L<Mozilla::CA>. If the Mozilla::CA module isn't available SSL requests will fail. Either install this module, set up an alternative C<SSL_ca_file> or disable hostname verification. This module used to be bundled with the libwww-perl, but it was unbundled in v6.02 in order to be able to declare its dependencies properly for the CPAN tool-chain. Applications that need https support can just declare their dependency on LWP::Protocol::https and will no longer need to know what underlying modules to install. =head1 SEE ALSO L<IO::Socket::SSL>, L<Crypt::SSLeay>, L<Mozilla::CA> =head1 COPYRIGHT & LICENSE Copyright (c) 1997-2011 Gisle Aas.

FTP # # The FTP URL scheme is used to designate files and directories on # Internet hosts accessible using the FTP protocol (RFC959). # # A FTP URL follow the syntax described in Section 3.1. If :<port> is # omitted, the port defaults to 21. # # 3.2.1. FTP Name and Password # # A user name and password may be supplied; they are used in the ftp # "USER" and "PASS" commands after first making the connection to the # FTP server. If no user name or password is supplied and one is # requested by the FTP server, the conventions for "anonymous" FTP are # to be used, as follows: # # The user name "anonymous" is supplied. # # The password is supplied as the Internet e-mail address # of the end user accessing the resource. # # If the URL supplies a user name but no password, and the remote # server requests a password, the program interpreting the FTP URL # should request one from the user. # # 3.2.2. FTP url-path # # The url-path of a FTP URL has the following syntax: # # <cwd1>/<cwd2>/.../<cwdN>/<name>;type=<typecode> # # Where <cwd1> through <cwdN> and <name> are (possibly encoded) strings # and <typecode> is one of the characters "a", "i", or "d". The part # ";type=<typecode>" may be omitted. The <cwdx> and <name> parts may be # empty. The whole url-path may be omitted, including the "/" # delimiting it from the prefix containing user, password, host, and # port. # # The url-path is interpreted as a series of FTP commands as follows: # # Each of the <cwd> elements is to be supplied, sequentially, as the # argument to a CWD (change working directory) command. # # If the typecode is "d", perform a NLST (name list) command with # <name> as the argument, and interpret the results as a file # directory listing. # # Otherwise, perform a TYPE command with <typecode> as the argument, # and then access the file whose name is <name> (for example, using # the RETR command.) # # Within a name or CWD component, the characters "/" and ";" are # reserved and must be encoded. The components are decoded prior to # their use in the FTP protocol. In particular, if the appropriate FTP # sequence to access a particular file requires supplying a string # containing a "/" as an argument to a CWD or RETR command, it is # necessary to encode each "/". # # For example, the URL <URL:ftp://myname@host.dom/%2Fetc/motd> is # interpreted by FTP-ing to "host.dom", logging in as "myname" # (prompting for a password if it is asked for), and then executing # "CWD /etc" and then "RETR motd". This has a different meaning from # <URL:ftp://myname@host.dom/etc/motd> which would "CWD etc" and then # "RETR motd"; the initial "CWD" might be executed relative to the # default directory for "myname". On the other hand, # <URL:ftp://myname@host.dom//etc/motd>, would "CWD " with a null # argument, then "CWD etc", and then "RETR motd". # # FTP URLs may also be used for other operations; for example, it is # possible to update a file on a remote file server, or infer # information about it from the directory listings. The mechanism for # doing so is not spelled out here. # # 3.2.3. FTP Typecode is Optional # # The entire ;type=<typecode> part of a FTP URL is optional. If it is # omitted, the client program interpreting the URL must guess the # appropriate mode to use. In general, the data content type of a file # can only be guessed from the name, e.g., from the suffix of the name; # the appropriate type code to be used for transfer of the file can # then be deduced from the data content of the file. # # 3.2.4 Hierarchy # # For some file systems, the "/" used to denote the hierarchical # structure of the URL corresponds to the delimiter used to construct a # file name hierarchy, and thus, the filename will look similar to the # URL path. This does NOT mean that the URL is a Unix filename. # # 3.2.5. Optimization # # Clients accessing resources via FTP may employ additional heuristics # to optimize the interaction. For some FTP servers, for example, it # may be reasonable to keep the control connection open while accessing # multiple URLs from the same server. However, there is no common # hierarchical model to the FTP protocol, so if a directory change # command has been given, it is impossible in general to deduce what # sequence should be given to navigate to another directory for a # second retrieval, if the paths are different. The only reliable # algorithm is to disconnect and reestablish the control connection.

Ideally there should be better Perl language support for this. =head1 METHODS There is only one method provided: =head2 _elem _elem($elem [, $val]) Internal method to get/set the value of member variable C<$elem>. If C<$val> is present it is used as the new value for the member variable. If it is not present the current value is not touched. In both cases the previous value of the member variable is returned. =cut PK ! �lF Authen/Digest.pmnu �[��� PK ! �uX � Authen/Ntlm.pmnu �[��� PK ! �}�,< < Authen/Basic.pmnu �[��� PK ! m�� � �( MediaTypes.pmnu �[��� PK ! >+�� � �C UserAgent.pmnu �[��� PK ! ���Y Y �K Debug/TraceHTTP.pmnu �[��� PK ! �~�c/" /" �N ConnCache.pmnu �[��� PK ! )l5�� �� �p media.typesnu �[��� PK !
