Hmmmm... perhaps you have a more recent version of the CGI generator....  
the Demo.cgi stuff in my MacPerl CGI folder all generates its own 
headers, and if I don't generate the headers myself from within my 
script, I get a "document contains no data" error....

Do you use CGI.pm?  That would explain it....

I tried this a while back on my server (WebStar 3, at the time, but via 
errors have verified with WebStar 4) -- my setup will not generate any 
headers for me.  I actually prefer it this way, as it allows my .cgi to 
generate a 302 (304?) header, which allows me to have a nice close to the 
interaction with my .cgi (a logout feature...)
