Re: [squid-users] Host based acceleration

Some relevant messages of mine found in the archives:

http://www.squid-cache.org/mail-archive/squid-users/199811/0609.html

Some information can also be found in the Squid FAQ, but I am afraid it may be
a bit misleading...

http://www.squid-cache.org/Doc/FAQ/FAQ-20.html

If someone could write up a new accelerator section for the FAQ that would be
nice. I am a bit too buzy with the code at the moment..
