Ssl – How to get Apache to serve SSL Bugzilla CGI from a subpage (NOT subdomain)

I'm trying to set up Bugzilla with SSL to be served by Apache from

https://www.foo.com/bugzilla

since I don't want to pay for an extra SSL cert to get a subdomain for bugzilla.

What is the best approach for this? Should I use mod_rewrite? There is normal PHP content being served on the other pages and I'm not sure how to direct just that one /bugzilla subdirectory to the Bugzilla installation directory.

Is editing the default-ssl conf file enough? Do I need to create another conf file? Right now https://www.foo.com/bugzilla gives a 404.
