Yes absolutely. I've setup a forward proxy, where I have to open a
port (8080) for people to use it. I've set the filter type to
text/html. So I guess it's definately an encoding issue. Any way how
to solve that? Strangely enough, the sed filter examples work no
matter what. So I don't understand why this doesn't.
I'm including the log output for the request...
