traffic coming over APM XforwardedIP not being recorded by IIS

Hi Jim,

IIS has a very poor support for X-Forwarded-For headers... 😞

I usually tend to write the original client IP into an additional cookie (via

HTTP::cookie insert name "OrigIP" value [IP::client_addr]

) and collect those information by turning on IIS cookie logging. Its much easier, doesn require any bits'n'bytes on your servers and may already satisfy your needs... 😉

If you're still looking for a native

X-Forwarded-For

support, then take a look to the following blog site. The site outlines and compares different techniques which are more or less supported/maintained by Microsoft or F5.
