USE="follow_xff" emerge squid set follow_x_forwarded_for allow localhost in squid.conf restart and got error parseConfigFile: line 2332 unrecognized: 'follow_x_forwarded_for allow localhost' Reproducible: Always Steps to Reproduce: 1. 2. 3.
I think I've fixed that in net-proxy/squid-2.5.10-r3. please test it and post here the results. btw, useflag is named "follow-xff", not with underscore.
I've tested the patch myself and it worked.
