Proposal (Was: When are and aren't two URLs the same?)

I wrote up a proposal on this.

It (hopefully) includes what we are doing already, plus the various  
comments that were made on this list.
Chances are I'm missing something ...

One example where this becomes important (even without going into  
Yadis-using protocols like OpenID and various LID profiles) is Yadis  
document caching.
E.g. if I have the Yadis file in cache for URL1, and URL2 is entered  
that is almost the same as URL1 but not exactly, do I have to try to  
re-fetch the document or can I assume that I can use the cached  
version for URL1?

The proposed algorithm would make this unambiguous, or so I hope ;-)
