My only interest in implementing CGI is to make scripts written for
other servers usable with gn. It would be silly to do an
implementation which wouldn't achieve that. What I was referring to was
something like requiring that for gn in the "path/cmd/args" part of
the URL the "cmd" must end in a ';'. Thus a URL would look like

http://host/foo1/foo2;/foo3

Any other semi-colons would have to be URL encoded. The PATH_INFO
would be "/foo3" and SCRIPT_NAME would be "/foo1/foo2;". Of course, the
filesystem name would be "/data_root/foo1/foo2". This
is CGI compliant and I think it would work with all the scripts which
work under NCSA httpd. This syntax shouldn't disappoint Rob, but it
disappoints me. I am still trying to think of a better way.
