Squid + Clamav to scan http proxy traffic

[Ovi]

Hello

Does anybody have experience with setting up Squid + Clamav to work as 
http proxy antivirus?
I've tried last days such setups with c-icap (which worked few months 
ago) + clamav + squid, without success.
Also I've tried using SquidClamav_Redirector, a python script, which 
partially works but is too slow.

If you have links with documentation regarding this issue or have any 
advice for me please tell me.

best regards
ovi
