in reply to Direct access to client socket in CGI/mod_perl?

It's been my experience that the POST data to Apache mod_cgi-based programs is delivered "live" and not buffered. (As an aside, that's why you can't rely on reading "content-length" number of bytes, because that's only what the browser suggested it was going to send.)

However, I have to ask the next question: how will your CGI know when the data is actually finished then?

Also, if there are any proxies in between, all bets are off.

    that prob would make pipelined requests kinda difficult. :) would it be better to allow the client to do some sort of client-pull operation, ie, send some sort of meta refresh response to the client, allowing them to poll the server for updates?

    See... having you tell me was exactly what I needed... because I was 99.9% certain that long ago, when I wrote CGI for the first time (before I was sucked into the world of Java app servers and crap like that), POST data arrived as soon as Apache got ahold of it. But, here I was, with my newly installed Redhat Linux 8.0 box... and I'll be damned if that didn't work!

    It would appear, and I don't actually have any documentation to back this up, but the stock Redhat 8 Apache 2.0.40 with it's bundled mod_cgi is somehow "broken." I am making this bold statement due to the fact that on other boxes where I am either using older Apaches, or even similar apaches which *I* compiled, the behavior was as expected. So, thank you!
