[9front] rc-httpd "write error" when using cgi

[Ralf Wissing]

Hi everyone,

i am currently experimenting with rc-httpd, and while it works flawless serving static sites i cannot get even a simple cgi script working. 

Here something i tried:

I have a simple rc script which echos a "hello world" html page (which i cannot include in this mail without getting rejected for using html mail). 

Then there is the following configuration:

File /rc/bin/rc-httpd/select-handler
%<------------------------
#!/bin/rc

PATH_INFO=$location
FS_ROOT=/usr/web

exec static-or-cgi /usr/web/cgitest.rc

%<------------------------


Running it with aux/listen1 i get only the following after visiting the page with a browser:

%<------------------------
echo: write error: Hangup
%<------------------------

I am sure that i miss something obvious... and i would now after a few hours tinkering appreciate any kick in the right direction.

This part works fine for me.

What is "it" that you are running with aux/listen1?  You should be
running /rc/bin/rc-httpd/rc-httpd not /rc/bin/rc-httpd/select-handler.

A glass of whiskey, a nights sleep was enough to let me see where i seemingly made an error:

Added "echo 'HTTP/1.1 200'" to the cgi script, now everything is working.
