Re: [PATCH] X-Forwarded-For

I'm going to take another stab at responding to this email. Hopefully I won't stick my foot in my mouth again.

I have a patch that does this that I use currently. When I figured out that I needed to preserve the original host header, I looked around for a patch and found none. So I just made the totally trivial change myself. Now, hearing this issue discussed publicly, I've looked through 2616 and have not found anything to indicate that we should be, or that it's even ok to, mutate the Host header, as we are now.

Does anyone know why we currently alter the Host header is proxy/gateway requests. Can anyone point me to the part of the spec. that says that this is ok or needed?

Thank you
