Backwards compatibility broken with URL()... for the better?

[Bluebie, Jenna]

In 1.5, to get a full url to ones camping app, you had to do:

this_url = 'http:' + URL('/some_action').to_s

Useful, for instance, in my openid consumer sample code, to give the  
openid doodad a return address

But in camping 1.9 off jud's gems, URL now returns actual url's with  
http: and everything at their fronts, which is rather snazzy... but  
breaking. Iunno, I kinda like this new fancy URL method that returns  
real URL's O_o

Jud's gem's session.rb still is including the IP address in the  
session hashing. I don't think we should recommend anyone use those  
gems till it's updated, I can only imagine how painfully frustrating  
it must be for user's in ISP's using AOL style load balanced  
transparent proxies who no matter what they do, can't get cookie  
session support to work in camping, with no errors or explanations.
