The thing is that I have severeal sites that i need to give ssl support and i can't find a way to tell the squid to act the same way that he acts for the non ssl connections. This is my setup to work with the non ssl connections. I try and it dosen't work by just telling to listen also in the port 443. Any links that can help? Here's an example squid config on my blog for a squid that listens on ssl: http://blog.hongens.nl/guides/protect-owa-using-a-reverse-proxy/ -- With kind regards, Angelo Höngens systems administrator MCSE on Windows 2003 MCSE on Windows 2000 MS Small Business Specialist -- NetMatch tourism internet software solutions Ringbaan Oost 2b 5013 CA Tilburg +31 (0)13 5811088 +31 (0)13 5821239 a.hong...@netmatch.nl www.netmatch.nl --
[squid-users] 2 cache_dir on the same squid server ?
hello folks, Can I specify 2 cache_dir directives for one squid server? I meant two cache_dir on 2 different disk to avoid disk failure ? Thanks!

Yes, you can. You can specify how many cache_dir's you want, each in the same partition, or in different partition or even in a different drive. But, it will not avoid problems if you have a disk failure. If the squid process try to write in a cache_dir, and this is not available (imagine that your drive is down, due to a failure), it will crash... But why are you worried about a failure? Are your disks failling?

Do you have any advice for me in this situation: 2 cache_dir on different disk is better or just one cache_dir on a disk with just one partition in it?

Ok... about the event of a bad day with your disks, I think that the right thing is to write a kind of daemon script to analyse the availabity of partitions, and if some of them are down, rewrite squid.conf without it and restart squid quickly. And about your situation, 2 or more cache_dir on different disk are better, 'cause the squid process can parallelize I/O requests, improving the transfer performance. (And sorry if I said some incompreensible thing, 'cause I'm brazilian and I still have a poor english)
Re: [squid-users] Question on Squid internals

Could somebody explain why this has happened? The exact same URL is requested from the command line and Squid has removed its copy of the page after the command execution. If the copy has become stale, going by the refresh_pattern rules, a TCP_REFRESH_MISS should have got logged instead of TCP_MISS. Its really weird that the copy on the disk was deleted, and a TCP_MISS was reported. did you check if the page is cacheable? Did you try fetching it with Cache-Control: only-if-cached header? It's quite possible that the page is not cacheable, so squid won't cache it, or the cache has expired... -- Matus UHLAR - fantomas, uh...@fantomas.sk ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
