Yeah, in 1.2.x you'll have to call setContextPath() on the application
settings object so it does the right thing (probably returns "/" in this
case).
There's very little you can do with version 1.2.x to make this nice, I'm
afraid. We've put a whole load of work in for 1.3.x to make it work
transparently behind a reverse proxy. For example, this case could be
handled elegantly using Request.getRelativePathPrefixToContextRoot(),
which will give you an appropriate number of "../" to prepend to make it
all work.
