[Zope] Virtual Hosting on ZServer Updated

[abg@comco-inc.com]

I'm pretty new to python, and am having a bit of difficulty with the 
AccessRule code Alan sugggested. I need to be able to map not only 
domains (bar.com), but virtual domains (foo.bar.com) to locations in 
Zope. This AccessRule works quite well for the former, but appears to 
ignore the prefix of the latter (foo).

Here's what I've tried so far:

I changed this bit of code:

hostname="_.string.split(_.string.lower(_.string.split(HTTP_HOST,
':')[0]),'.')[-2:]" 
          domainname="hostname[0] + '.' + hostname[1]" 
          vhmcode="VHosts.gethostfolder(_.None, _, host=domainname)"

To this:

hostname="_.string.split(_.string.lower(_.string.split(HTTP_HOST,
':')[0]),'.')[-3:]" 
          domainname="hostname[1] + '.' + hostname[2]"
	    domainname2="hostname[0] + '.' + hostname[1] + '.' +
hostname[2]"
          vhmcode="VHosts.gethostfolder(_.None, _, host=domainname)"

How do I tell AccessRule to use one method (gethostfolder) for those
requests that are in bar.com format, and another method for those requests
that are in foo.bar.com format?

Also, I'm really not sure if the changes I've made above are going to screw
anything up.

Any help will be greatly appreciated, and (hopefully) returned at a 
later time.

Thanks.
