Thanks, Tino! But will this work for my own python modules? I have two
URL paths:

1. /z  -- standard managed zope area
2. /app -- my python module which is a ZPublisher-based app that
doesn't have /manage or the other "managed zope" stuff

I have #1 working with SiteRoot (will switch to VHM). No help needed here.

For #2 I modified z2.py per Amos' write up: "How to Publish Your Own
Python Modules" (http://www.zope.org/Members/Amos/ZPublisher)  ...
(thanks, Amos!). But I can't get the "base href" set properly for
this.

Changes to z2.py shown below. I really appreciate any light people can
shed on this. Remain willing to pay for help.

Thanks!
Royce


In z2.py I have:

            zh = zhttp_handler(MODULE, 'z', HTTP_ENV)
            hs.install_handler(zh)

            # royce 8/22/04
            sys.path.insert(0,'/app')              # add MyModule to
the Python path
            # create a handler
            my_handler = zhttp_handler('webapp/sessionMgr',
'ex/sessionMgr', HTTP_ENV)
            hs.install_handler(my_handler)              # install it
in the http server
