most http headers are stored as environment variables starting with 
HTTP_ for the script (except the authentication header, for securitry 
reasons).

So, it's best to dumo the environment in your script to the screen or to 
a file first and then have a look what's around and how it is  named.


A simple test shell script would be:


#!/bin/sh
printf "Content-type: text/plain\n\n"
set
exit 0
