The lwpcook documentation (that comes with the LWP bundle) provides very helpful examples of how to use the LWP modules. Here's the section on POSTing data: 
POST

There is no simple procedural interface for posting data to a WWW serv
+er.  You
must use the object oriented interface for this. The most common POST
operation is to access a WWW form application:

  use LWP::UserAgent;
  $ua = new LWP::UserAgent;

  my $req = new HTTP::Request 'POST','http://www.perl.com/cgi-bin/BugG
+limpse';
  $req->content_type('application/x-www-form-urlencoded');
  $req->content('match=www&errors=0');

  my $res = $ua->request($req);
  print $res->as_string;

Lazy people use the HTTP::Request::Common module to set up a suitable
POST request message (it handles all the escaping issues) and has a
suitable default for the content_type:

  use HTTP::Request::Common qw(POST);
  use LWP::UserAgent;
  $ua = new LWP::UserAgent;

  my $req = POST 'http://www.perl.com/cgi-bin/BugGlimpse',
                [ search => 'www', errors => 0 ];

  print $ua->request($req)->as_string;

The lwp-request program (alias POST) that is distributed with the
library can also be used for posting data.

I've used the lazy approach to good effect.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
