I think I've just discovered the trick which makes it work or break. When I have this line as just "redirect prefix..." then I get a redirect response to "http://%[hdr(x-original-site),field(1,.)].example2.com/" When I add "http-request" to the start of this line, then it works fine. I don't understand from the documentation the difference between these two directives, however from my initial tests it does seem they are different and http-request runs earlier in the processing of a response than just a bare "redirect". It would be useful if the documentation better explained the %[] operator and when it is allowed to be used.
