in reply to Direct access to client socket in CGI/mod_perl?
merlyn has already said that mod_cgi gives you a live connection to the socket, so you just read from STDIN in your CGI program as you would normally. People almost always want decoded form/url-encoded name/value pairs so you will see them use CGI.pm, but there is technically nothing to stop you reading STDIN directly. I use this in CGI programs that support machine/non-human HTTP clients, which POST and PUT XML and YAML in the body of the request, rather than the usual form data. (The contents of the Content-type: header change to "text/xml" or whatever to reflect this, obviously.)
