Updated X-Forwarded-For ISAPI Filter from F5

A new version of Joe Pruitt's (from F5) X-Forwarded-For ISAPI Filter was made available recently.  This update targets both 32 and 64 bit versions of Windows 2003 and 2008, has been tested under IIS6 and IIS7, and adds some new features like Proxy Chain Support and Alternate Header Names. 

With the old filter, if your request passed through multiple proxies that supported the X-Forwarded-For header, instead of actually seeing the IP address of the end-user, you'd see the IP address of the second to last proxy that this particular request went through.  This updated filter addresses this issue.

Alternate header name support is if you are using a header name other than X-Forwarded-For to store the client IP address, you can specify that header name in an .ini file so that the filter knows what to look for. 

I've just downloaded it but have not tested it yet myself, (let alone deployed) it but I'll post updates when I do.

The source code is included.  Joe would appreciate hearing about any updates that you might have made.  There does not appear to be a restrictive license in place.
