I figured out how to fix my problem. I always make cgi_interpose_input() get called for POST methods. It must have to do with what the comment in the code said -- that the CRLF vs. LF issue for some browsers screws things up. So, I have PHPWIKI working as a CGI script now! Yey. http://marc.theaimsgroup.com/?l=thttpd&r=1&w=2
