OSU-HTTPd Patch
Author: Charles Lane <lane@duphy4.physics.drexel.edu>
Date: 11-Jun-1999 (reformatted & this header written 7 Feb 2000)
Applies to:  OSU HTTP Server, version 3.3b...other versions too?
Description: 
   This code checks for HTTP headers returned from a CGI
   script and dumps the CGI output for an error return if the CGI 
   doesn't supply what this code considers a "minimal" amount of
   header information. 

   This runs into problems with handling some "newfangled" requests 
   via CGI (primarily DELETE, RENAME, PUT, etc. used by Netscape's
   Roaming capability). 

   This patch contains a minor typo fix (for the length of "STATUS:",
   and makes the s/w less picky about what gets returned from the CGI
   code.   

   Apply patch from the OSU HTTP server's "home" directory.
