Quick question (I think).

I'm POSTing data via LWP. As far as I can tell, I'm sending all the data in a very kosher manner. However, I'm getting nothing back (literally nothing... not even empty HTML tags). If I don't send any post data, I at least get an error page. At any rate, I'm sending this stuff to a server that's not mine, so I made a little test PHP page to see if I'm sending the right stuff. There are a few variables with a "." in their name (eg; ".challenge", ".md", etc.). When I dump the $POST array in my PHP script, they show up as "_challenge", "_md". Am I to assume that I'm sending the variables correctly and PHP mangles the _ & ., or can I assume that LWP is doing that before it sends them?

For giggles, here's the code. 
my $ua  = new LWP::UserAgent;
my $req = new HTTP::Request POST => $url;
$req->content_type('application/x-www-form-urlencoded');
$req->content($post);
my $res = $ua->request($req);
print $res->content;

I've made sure that $url and $post have the correct strings in them.

Thanks.
