Are you looking to add X-Forwarded-For functionality to
your ISA Server proxy infrastructure like Squid, Apache, F5 Big-IP, Blue
Coat, Cisco Cache Engine, Netcache etc? Now you can! Winfrasoft X-Forwarded-For
for ISA Server adds the ability to track the source
IP address of a client PC through a proxy server chain.
This is very useful for log analysis when branch offices
connect to the Internet via a head office proxy server,
and many other scenarios where multiple proxy server
layers are used.

How it works
Making proxy requests: The ISA filter adds the X-Forwarded-For
field to the HTTP header of web requests leaving the ISA
Server. The new field contains the IP address of the
original web browser client PC.
Receiving proxy requests: If the ISA Server receives a
proxy request which contains the X-Forwarded-For
field in the HTTP header, the filter will log the XFF IP as the client IP address
instead of the
IP address of the requesting proxy server. The IP address of the
requesting proxy server is not lost, it is added to the Filter
Information field in the ISA Server logs.
Security: In a forward proxy scenario, if the ISA
Server is not configured with a web chaining rule it
will not add the XFF header, this helps to prevent your
internal server names being revealed to the Internet. NB: You should never trust X-Forward-For header
information that originates from outside of your
organisation as the field is not signed or
authenticated.
Note: X-Forwarded-For for ISA Server uses the same
HTTP field format as other vendor implementations of
this technology and should be compatible with other
proxy server solutions, although this has not been
tested.
