ok understood. I took the rule out and tested also disabled the rewrite engine but no luck. still the backend site gives links as original.
there is one thing that I belive it might be affecting
the proxy is calling the back end server with an ip..
but the backend server has a rewriter that sets a hostname ..
would it be possible that the match of the rewrite is not being done because the lsws belives the match is the ip and not the rewriten host on the backend?
