Helo, I can patch only the squid 2.5 stable 4 with x-forwarded patch. This works correctly. But if use this patch with squid 2.5 stable12 ( or higher stable 4) I can do it with errors. Such as : Hunk #1 FAILED at 318. 1 out of 1 hunk FAILED -- saving rejects to file src/delay_pools.c.rej How can I patch the latest squid version with follow_xff-2.5.patch correctly ? Thanks
