The rev_proxy code is experimental. I think some have used it
successfully but YMMV.
Klacke and I recently chatted about this code. He has no time to work
on it at present, and I don't have any use cases for it myself that
would help me improve it. However, if people are willing to submit
test cases for it, especially cases that should work but don't, I'd
definitely fix any problems those cases cover.
Andrew, any chance you could whittle your code down to a minimal test
case that shows the problem?
