Remove X-Forwarded-For header in Squid 3.0

Question

Some months ago I was working with Squid 3.0 and managed to get rid of the X-Forwarded-For header completely. Now I am trying to do the same thing but I do not seem to hit the nail.

I have tried forwarded_for off but that does not remove the header, it just inserts unknown in place of the client IP.

I tried header_access X-Forwarded-For deny all but I receive an error about invalid directive. Looking in the function reference it seems that this directive is deprecated in 3.0.

I tried forwarded_for delete but this is only available from 3.1.

Any suggestions?

For specific domains you can use

acl NoXForwardedFor dst "/usr/pbi/squid-amd64/etc/squid/NoXForwardedFor.txt"

request_header_access X-Forwarded-For deny NoXForwardedFor

where NoXForwarded.txt contains domain names.

you can set forwarded_for directive to truncate

forwarded_for truncate

this will remove all existing X-Forwarded-For entries, and place the client IP as the sole entry

For more about this directive visit squid : forwarded_for configuration directive
