Sorry, I forgot to mention that I had fixed the request_uri issue as well.
IIS does indeed not supply 'REQUEST_URI', so my workaround for an issue with
this (I think I fixed this in 1.3.0 already and did not think about it) was
        self.request_uri = env.get('REQUEST_URI', '%s'%self.script_name)
(this is probably not quite correct, I just needed something useful in that
variable for the request.url variable that is used to find a wiki in a farm
config).
Thus, the first check was always true in my case and the problem was
self-made. Nevertheless I think that
  server_software.find('Apache/1.3') == -1
was meant to be
  server_software.find('Apache/1.3') != -1
if the first check was intended for apache only.

In any case, changing this fixed my problem just fine. The second check was
executed and did its magic.

However, as there are some places that use self.request_uri there should be
a safe setting of this variable other than '' even in the case that the
server does not deliver 'REQUEST_URI'. My fix is probably not the best way
to do so.

Unfortunately my wiki farm (with a total of 4 wikis, a lot of patches and
special development including forms-based database access, currently
migrating from 1.1 on IIS 5 to 1.3 on IIS 6) runs on our intranet and I
can't supply an external url (which means I have to solve all the riddles by
myself ;-(
