I read the RFC recommended,I know what I should prepare (and I already knew) for my script, but the question is how to send it to the script.

client makes a request through socket , your server reads headers, then

Populate a local %ENV

dispatches/calls/invokes a process ,

through pipe, fork, whatever, see perlipc, Capture::Tiny

put http request BODY on STDIN

Collect output from STDOUT

log errors from STDERR

After timeout, or whatever, return/generate/forward a return HTTP request back on socket to the client

I already linked examples in Re: How a web server sending data to a CGI perl script ?
