Re^5: How a web server sending data to a CGI perl script ?

As you've read the RFC, maybe you can tell us what parts of chapter 3, Invoking the Script you've already implemented, and where your server still fails.

Update: Chapter 4.1, Request Meta-Variables tells me:

Meta-variables contain data about the request passed from the server to the script, and are accessed by the script in a system-defined manner.

The traditional system-defined manner is using the environment (%ENV) to pass these values. See also chapter 7, which discusses the different operating systems and their system-defined ways of communicating the variables to the child process.

In fact, I think that's nothing to do with RFC. A CGI script can be in Perl, Python, PHP, or whatever, it's the spec only, which is a "WHAT" but I am asking "HOW". Consider I have already prepare everything (is needed for me at this moment, actually), but as said in my OP, the limitation is I have to do all the rest within my server's code. My server can communicate with the browser by all means. I don't know "the how" is how to pass the parameters that I've prepared to my target CGI script, so when my CGI script got triggered, it's just naturally have all the %ENV variables ready or a opened STDIN is ready for read().

The RFC describes what the server must do that the script finds the information. The "how" also is evident from the RFC. You stick the informatin into `%ENV`. Also consider looking at HTTP::Server::Simple::CGI::Environment or HTTP::Request::AsCGI, which set up a CGI environment.	[reply] [d/l]
