Hello, We have two proxies which allow our users access to the internet, one as live box and one as a backup. Both boxes are running Gentoo and Squid 2.6 STABLE16. Recently the live box was replaced with a new server. The OS and Squid were installed as before with the same configuration file. It now seems to have developed a problem when accessing HTTPS sites that require a certificate. When browsing to the site, it prompts for which certificate to use, then gives a little warning about how the hostname does not match the URL and then loads half the page. After about 1-2mins, a 404 error is produced in the areas which it hasn't loaded The main issue is that the backup proxy, which is running the same version and same configuration file, does not produce this error and loads the sites perfectly I have tried re-emerging Squid, building it from source myself with the same options and have even copied the binary over from the backup server to the live one, but it still refuses to load the page. I know the big change is the new install (the old server has been there for years and just updated from time to time) but I'm wondering what could be causing the problem. Other HTTP and HTTPS sites work fine The log files don't show any errors. The only difference being the amount of data transferred is a lot less on the live one than on the backup one when connecting to the problem sites Is there something obvious I should be checking? I would have thought that even though I've installed a new OS which has newer versions of bits and pieces than the backup one, this wouldn't make much of a difference. Perhaps I'm wrong?
