duplicated IP in X-Forwarded-For
Hi there,
configuring frontend-backend (apache 1.3.27) I noticed last ip in
X-Forwarded-For is duplicated. Seems (from proxy_http.c), mod_proxy now
generates X-Forwarded-For itself. Earlier versions ( I checked 1.3.9)
doesn't generate X-Forwarded-For.
Do we need mod_proxy_add_forward.c now ?
A small problem arises if I don't use mod_proxy_add_forward.c -
I can't log X-FORWARDED-FOR in proxy's access_log via \"%{X-FORWARDED-FOR}i\"
Regards,
Oleg

That was my fault ! I wrote X-FFORWARDED-FOR instead of X-FORWARDED-FOR
^
Now everything works fine. Thanks for help.
I think I'll play with mod_accel instead of mod_proxy.

I don't quite think so. I'm really quite baffled as to why he can't log any
more. I'm thinking that's more a problem with mod_log_xxxxx (whatever might
be used now) than a problem with mod_proxy. Oleg, are you sure you've
compiled in whichever logging modules you used to have compiled in (or DSO'd
in)?

patch mod_proxy to do what mod_proxy_add_forward was doing and submit the
patch for inclusion in the next mod_proxy release?

Thanks Issac,
I believe so now. The only problem is how to log those ip's by proxy server.

*Grins* I remember when a couple of us blindly ported
mod_proxy_add_forward.c to Apache 2 just after it was officially declared
"stable", only to test it and discover the same thing for ourselves :-) The
answer is that it's a standard part of mod_proxy since (I believe) 1.3.26...

Issac

I've never installed it. mod_proxy is doing it on its own for recent
versions of apache.
