[squid-users] X-Forwarded-For Header and Rewriter

Hi,

does anybody know if it is possible to access the X-Forwarded-Header inside of a rewriter script (squid used as reverse proxy). AFAIK, there is only the ip-address of the requesting server available which may be the ip of another cache-server.

Background: We have another external cache server that queries our squids and we want to pass the client ip to an external script which makes decisions about the client ip: e.g. redirection to a special url if certain ips are there.
I know that it is easy to trick the x-forwarded-header to fake ips, but nevertheless.

if I use something like external_acl %SRC with an external script I can only say:OK or ERR, i.e. access or not. But I want to give the client different urls back depending on its ip.

Or is there any other possibility to make such decisions (with the x-forwarded-for header information) outside the redirect script?

thx in advance,
max
