Re: HAPROXY and POUND X-FORWARD

Hi All,


This may be useful for someone. It's a free App we wrote to enable
Microsoft IIS servers to log the X_Forwarded_For IP. In fact you can
change the HTTP header value to be logged in the registry.

I Hope it's useful for someone.

Hi Chris, 

 

In looking at the pound website, it looks like it does insert an
X-Forwarded-for header:

As long as HAProxy doesn't re-write the header, it should get passed to
your servers.

We are using Pound to terminate incoming SSL traffic and then we forward
to the packet to a HAPROXY server for load balancing. 

 

Pound sees in the client IP address of our external web browser in its
logs, which is great,, but when Pound forwards the traffic to HAPROXY,
HAPROXY sees the source IP as being Pound and not the real external IP
address.

 

Is it possible for Pound to send the real source IP address to haproxy
and have haproxy display that IP address in its logs instead?

 

Basically, I want haproxy to see the x-forwarded IP address.

 

Thanks,

 

Chris.
