[Zope] proxy tool for Zope/Plone

[Max M]

I need to integrate a few external .asp based web tools into a plone site.

Instead of recoding them and converting them to Zope products, I want to 
do it by "importing" them into Page templates.

What I need is basically to browse another webpage through a Plone Page 
template, so that I can keep the look and feel of the Plone site. Just 
as if I jused frames or iframes.

I have made something similar in the past, but not as complete.

I can see this as a usefull tool in many situations. So I wondered if 
anybody has done something similar allready, and have any experiences 
they want to share.

I especially wondered if there would be an advantage to using 
Squid/Apache as a middle layer, so that I wouldn't have to do the url 
rewriting myself :-s

Any knowledge of documentation/pitfalls would also be appreciated.
