Re: Args and Params.

I'm not sure about this but the problem might be that CGI is attempting to
read the POST data first, and since POST data can only be read from the
socket once, $r->content hangs.

You might want to look into either

1. caching POSTed Data:
http://perl.apache.org/guide/snippets.html#Caching_POSTed_Data

2. using Apache::Request, a module that implements the
CGI::param method, but does it in mod_perl and is a lot faster
