[Zope] Catching external links - Ideas ?

[Bjoern Kriews]

Hi !

I am pretty new to Zope and I am looking for a way to allow content authors
to link to external sites through a logging redirector.
I would like to save those people from typing the redirector-URL and 
having to URL-escape some characters.

What I want to provide the content writers with is something like:
<!--#ext "Look, there" href="http://some.where?query%20string#name"-->

and get 
<A HREF="/redirect?http%3a%2f%2fsome.where%3fquery%2520string%23name"
onMouseOver="...">Look, there !</A>

If you have an idea on how to achieve this with Zope builtins or
on the best way to implement it, please give me a hint.

Thanks & regards, 
  Bjoern
