I suppose you mean using Crypt:SSLeay via LWP:

#!/usr/bin/perl
use strict;
use warnings;
use LWP::UserAgent;

my $ua = LWP::UserAgent->new();
my $resp = $ua->post(
       "https://www.website.ws/members/index.dhtml",
        [
            userid   => 'foo',
            pwd      => 'bar',
            language => 'english',
            form     => 1,
            page     => '',
            func     => '',
            pagedrop => '',
        ]
    );

if ($resp->is_success) {
    print $resp->decoded_content;
} else {
    print $resp->status_line;
}

Thanks. I do not see a use Crypt::SSLeay line. Is there a clear definition of the parameters to be passed in the post. I understand it will be dependent upon the number of fields on the page to complete, but I am confused on what other parameters are required versus optional. For example - language.

I do not see a use Crypt::SSLeay line.

That's why I supplied the strace as 'proof' :) — Crypt::SSLeay is loaded automatically for HTTPS requests.

Is there a clear definition of the parameters to be passed in the post...

That's entirely site/URI-dependent. I just made a request using Firefox and traced it using the "Live HTTP Headers" addon to see what's being sent.
