Hello Amos! Glad to get your answer!
1. I have tried to use %>p specifier for adaptation_meta directive. But it seems does not work that way I used it. I specified it in squid.conf: adaptation_meta X-CLIENT-SRCPORT %>p I found that specifier ony in logformat. May be you mixed it up? 2. About mapping port transparently. How does it help to get (at least) mapped port number in ICAP? 3. I would like to track any software. Especially software which use "User Agent" field not legitimately or event does not fill it at all. -- /BR, Alexander Mon, 15 Dec 2014 17:32:34 +1300 от Amos Jeffries <squ...@treenet.co.nz>: >-----BEGIN PGP SIGNED MESSAGE----- >Hash: SHA1 > >On 13/12/2014 9:09 a.m., Александр Бубнов wrote: >> I do not need to map it back remotely.
