I've found the following page the most useful in this respect:

Your case sounds just like ours, so here's how we do it:

Let's say:

- you want to serve http://www.xx.com/zopeit
- inside your zope this corresponds to localhost:8080/sites/xx.com

In the root of your zope you should have a VirtualHostMonster, named
anything you like.

In you httpd.conf, you should have:

## with all the other AddModule and LoadModule:
LoadModule rewrite_module     modules/mod_rewrite.so
LoadModule proxy_module       modules/libproxy.so

AddModule mod_rewrite.c
AddModule mod_proxy.c


## in your virtual hosts section:

<VirtualHost 66.66.66.66:80>
        DocumentRoot /var/www/anything-goes
        ServerName xx.com
        ServerAlias www.xx.com

        RewriteEngine on

        RewriteRule ^/zopeit/(.*)$
        http://localhost:8080/VirtualHostBase/http/%{HTTP_HOST}:80/sites/xx.com/VirtualHostRoot/$1 [L,P]
</VirtualHost>

That's it!

- the VirtualHostBase means "please use VHM to re-write urls"
- the http means use the http protocol (as opposed to https)
- the %{HTTP_HOST} means use the host part of the request as the host
  in the rewritten urls, i.e. www.xx.com or xx.com; you could replace
  %{HTTP_HOST} with 'xx.com', but then www.xx.com would be re-written
  to xx.com

- :80 means use port 80 in the re-written urls, i.e. don't show an
  explicit port

- /sites/xx.com/VirtualHostRoot/ means the site is rooted in Zope at
  /sites/xx.com

- $1 means pass on the path information to zope as it is,
  e.g. "http://xx.com/zopeit/search?fish=cod" becomes
  "http://localhost:8080/sites/xx.com/search?fish=cod"

Hope this helps,

Felix.

P.S. if this doesn't scratch your itch, ask the list again, perhaps
including the relevant bits of your conf files, and you'll get there.
