[Catalyst] configurable base url?

[Pablo Collins]

Hi all,

I some catalyst apps whose different versions I'd like to make available 
by base path, like

http://mydomain/myspecialapp/version1.2/
http://mydomain/myspecialapp/version1.3/
etc.

I was planning on using a lighttpd or apache proxy to several 
Catalyst::Engine::HTTP processes running the different versions. That 
part is straightforward.

What I'm hung up on is how to tell catalyst to throw away the 
/myspecialapp/version1.3 part of the url and start the controller 
matching from there. I'd like to not have to change the names and 
namespaces of the controllers based on their versions if possible.

Instead I'd like to be able to put the application root url in the 
config and have it just work.

Is this possible / relatively easy to do?

Thanks much.
