Grabbing HTTP Header

[Dan Shafer]

Thanks, Monte.

I got your post on the Rev list. The engine is in the right place and referenced correctly. A simple CGI that doesn't involve parsing the incoming headers but just puts up a message works just fine.

I have set the permissions on the script to 755, so that is right as well.

I just can't make the very script that you present below run on my system and I'm completely befuddled as to why. One of the problems is I can't figure out where on OSX there might be a log I can check to see more precisely what's going wrong here.

Arrggggh.
