[Zope] Serving a sub-folder: 2nd Try

[Evan Simpson]

Having burned myself on the first try, here's a second approach which (knock
wood) appears to do everything right.  It's simpler, too.

Forget editing App/manage_tabs.dtml, all we have to muck with is
ZPublisher/Publisher.py

Once again, find "URL=request.script" around line 360.  Directly after it,
insert:

        omit_steps=request.environ.get('ZOPE_OMIT_STEPS')
        if omit_steps:
            omit_steps = int(omit_steps)
            request.other['PATH_INFO'] = '/'+join(path[omit_steps:], '/')

then, down around line 400, change "URL="%s/%s" % (URL,quote(entry_name))"
to:

            if omit_steps:
                omit_steps = omit_steps - 1
            else:
                URL="%s/%s" % (URL,quote(entry_name))

Now, in your rewrite rule, you can do something like:

RewriteRule ^/(.*) /subsite/$1 [E=ZOPE_OMIT_STEPS:1]

I've tested this with management screens, Confera cookies, and normal use,
and it seems solid.  If you're bothered (as I was) by the lack of a root
link in the management screens' parent list, you can change line 110 of
App/Management.py from:

         if not path: return ''
to:
         elif path: path=['.']+path
         else: return ''
