[Zope] Serving multiple Zope domains on Apache?

This issue has been discussed before, and at length, but I could find nothing conclusive in the archives. The problem seems to be Zope's handling of SCRIPT_NAME et al, and how you have to patch ZPublisher somehow to get URL rewriting working correctly. What's the status on this? I think the community -- including myself -- needs a definitive HOWTO on setting up serving of multiple domains with Apache, Zope, mod_rewrite, and mod_pcgi. How are the Zope hosting providers doing it? Is there a way to do it without patching Apache or Zope? And so on. -- Alexander Staubo http://www.mop.no/~alex/ "Reality is that which, when you stop believing in it, doesn't go away." --Philip K. Dick
