Too bad for them. The only other way to support session is by encoding
the session id in the request, and it's much more of a security hole
than cookies.

How do you think redirections are implemented in frameworks that have
syntactic sugar for this ? At the HTTP level, redirections are done by
sending the corresponding status code and headers. And writing your own
redirect() function is pretty trivial.

And you don't want to use cookies ? Lol.

*Please* take some time to understand how HTTP (and CGI) works - it will
save you a lot of time.
HTTP is a *stateless* protocol, which means that the server itself
forget everything about a request as soon as it is done handling it. So
a request must provide *all* necessary informations. The *only* way to
maintain some kind of 'session' with HTTP is to make sure the client
passes the needed session identifier back to the server. And the 2 only
ways to do it are to :
1/ use a cookie
2/ put the identifier in the request (usually in the query string part
of the url).
The fact that Python's CGI module doesn't offer out of the box support
for sessions has no relation with how sessions work.
BTW, you may want to have a look at Webstack, which provides a common
API over cgi, mod_python, and some other deployment solutions. This is a
pretty boring API (no magic, nothing fancy, nothing sexy etc), but it's
somewhat higher-level than plain CGI and it offers support for sessions
(yes, with cookies - like 99,99% of web programming solutions).
