[Zope] How to get the url without the domain part, using <dtml-in>?

Is it possible to return the absolute url without the domain/IP part, while in an iteration? With absolute_url I get this: http://100.0.0.1/folder0/folder1/folder2/current_object , and instead I'd like to have this: /folder0/folder1/folder2/current_object I tried the BASEPATH special variable, but it seems that it doesn't work within <dtml-in>. The other downside is that it needs an argument to get to know the nesting level of the object. Has anyone found a workaround? Thanks in advance, Ausum
