Yes, I caught that problem before posting it, but since Zope ignores
the adapter anyway, it didn't seem worth fixing yet. :-) First I need
to understand whether AbsoluteURL's failure to adapt its context to
ILocation is a bug, or something I don't understand about the whole
Zope approach to things (I hope very much that it's the former, and,
if so, am willing to submit a patch myself).

Wow! I didn't know Grok had a "getSite()" method! That's exactly
what I needed last night when, after patching my own version of
AbsoluteURL, I never could find a way for my Adapter to reference the
I have just tried your suggestion, and it works perfectly. Thank you
for your help!
