Did anyone use Squid + ICAP server?
Well, I found free ICAP-server written on Python on the icap-server.sourceforge.net.
I took the squid with builded in ICAP-client there too. I set up all it and configured ICAP-server usage in squid.conf.
But I have the following problem.
When I'm loading a _first_ page through the proxy (Squid+ICAP) - all is OK. But then when I'm trying to load another page, SQUID process gets CPU usage for about 100% for all next time. ICAP server and appropriate servlets've worked good and I 've got the page but SQUID CPU is still about 100%. After some time, I can see that the percent of its working in the system mode is increasing up to about 50%. It seems that it makes some read-write operations with cache or something else in the system mode.
I've downlowded Squid 2.5-4Stable with builded in ICAP-client, but it seems that this version isn't compliant with Python ICAP-server (I have the latest version from site) I have.

We need to complete this work in short terms so there is no time for digging sources trying to find out the problem in squid icap-client realization, so If someone have experiance with using Squid + ICAP and can suggest me some Squid version + some free ICAP server = stable working, I'll be very appreciate.
