Greetings Rémy,

   Thank you for volunteering.

I'm happy to mentor you through the code for this if you need any
assistance. Here are a few links to help you with your code explorations.

What documentation we have for 3.x can be found at:
   http://squid.treenet.co.nz/Doc/Code/

We have a portage page to track the patches in 2.x. It's not very up to
date right now.
  http://master.squid-cache.org/Versions/v2/2.7/changesets/port.html

The main storage URL patches begin with patch #11738 (search for
"support rewriting the URL used for store"). There are quite a few of
the bug fix patches following it. Plus one more recent bug fix at:
  http://www.squid-cache.org/Versions/v2/HEAD/changesets/12695.patch

Initial major task is porting the patch so that it will build and run in
Squid-3. Style changes to make it fit fully with 3.x need to be done
separately after the port work is complete. Doing them early makes the
extra bug fix ports harder.

I hope this helps, and am looking forward to the results.

Amos
