Hello, I'm running squid-2.7 for reverse-proxy (primarily use its http/1.1 features). But I got many warnings in cache.log: 2008/02/25 15:48:09| ctx: exit level 0 2008/02/25 15:48:09| ctx: enter level 0: 'http://res-js.mail.xxxx.com/zh_CN/htmledition20080131/js/all.js' 2008/02/25 15:48:09| storeSetPublicKey: unable to determine vary_id for 'http://res-js.mail.xxxx.com/zh_CN/htmledition20080131/js/all.js' What's that? Is this serious error? thanks!
