Hi, Consider using VMware ESX/ESXi 4.0 and FT. I have successfully used, tested and demonstrated VMware ESX/ESXi 4.0 and VMware FT services performing web scanning and proxy services. In the demonstration simply pull the power plug or "reboot" one of the ESX/ESXi servers. The time to switch to the secondary system was in the ms range - many times simply pinging the devices the switch was not detectable. In each test - all sessions remained active - including download of data / files such as ISO images, or streaming video. Each server running Squid was CentOS based, running latest kernel, including VMware tools. At the time I was using Squid 3.0 (exact version I cant recall, but it should not matter). Let me know if you need any further information.
