Yes. Thank you. Works great.

URL1 includes the domain, so for every "click" there will be a
DNS-request (the common Browsers don't cache DNS, IIRC).

I use this

<!--#call "REQUEST.set('path',PATH_INFO)" -->
<dtml-if "path[-1]!='/'">
        <dtml-call "REQUEST.set('path',SCRIPT_NAME+path[:_.string.rfind(path, '/')])">
</dtml-if>




<a href="<!--#path-->/">x</a>

and no DNS-request is needed.
