I have seen couple questions about trying to force of linux distributions mirrors into squid cache. This is nice but it missed the whole point of squid.. let say I do have a log of the proxy traffic domains and I see a server or a domain that takes a nice amount of traffic like debian deb files etc.. for a sysadmin to turn on a small VM with 10-20GB HD size can take about couple minutes or a little more. configuring it as a mirror also can take minutes... posting it as a mirror can take more then a day but then you got it right. instead of just force your clients a cache and harm the CIA of data just turn on a MIRROR if needed. it adds a small maintenance TASK but compared to caching all of the site as part of the cache and as a store?? also a mirror can be even a reverse proxy to the main site or another local\closer mirror. This way you do not harm the integrity of the data and also make sure that the mirror is a cache only mirror with a longer cache period which can help a lot. Eliezer
