Hi John,

Thanks for your help, it was the problem. I simply added the option http-server-close in my config and it's ok now !!

Regards,

Christophe

I believe your problem is because, for keepalive sessions, HAproxy is only adding an X-Forwarded-For header on the first HTTP transaction of the keepalive session. This can be alleviated by using "option http-server-close", which allows keepalive on the client side, but uses Close mode on the server side. The X-Forwarded-For header will then be present on all HTTP transactions.

I installed HAProxy on 2 Debian server for loadbalancing 6 webserver (IIS).

All works fine but I've a small problem.

In IIS, I added an ISAPI filter to read the X-Forwarded-For value.

In the IIS log file, I've a mixed of my loadbalancer IP (192.168.0.3) but also the official IP (xxx.xxx.xxx.xxx), for example:

Do you have an idea? I don't understand where's the problem.

Thanks for your help.
