We use Routes for generating our URLs and I see it has a URL prefix option.
It also appears to be pretty easy to set up. See:
http://wiki.pylonshq.com/display/pylonsdocs/Configuration+Files (under
PrefixMiddleware)
Just by putting in these four lines into the config file gives you a prefix
to the relative urls in CKAN. It appears to work ok for me, but there may be
occasions when we have hard-coded things though, so if you spot any, let us
know.
