Hi, I have running squid as reverse proxy with a rewrite-program, that rewrites URLs "/abc/1234", "/def/1234" and so on to "/1234". The backend application server only sees the rewritten URL, but I want the application server to know the "original" URL. I though about adding a new header field in the proxy request, like "X-Rewritten-From: /abc/1234"... Can I do this? How? Or any other solutions for this use case? Thanks and regards -stefan-
