I eventually tested with a nightly build of safari, and the bug has  
been fixed. Still, we need the workaround, I suppose.

Right, but if the cgi script is not HTTP-aware and returns a body,  
apache DTRT and strips the body when answering HEAD requests, doesn't  
it? Granted, doing the right thing directly in the cgi script is  
better...

Hmm I doubt the 204 solution would be very well implemented, but  
worth a try.
I tested the idea of not sending the Content-Length: and replacing  
with print "\n"; - didn't work. print "\n\n"; did work, but that's  
rather equivalent to my previous solution...
