HI, Squid-Users We are using several squid accelerating one web site which services flash media content for authorized end users. Recently we met a strange problem ,hope some one can give out a hand . After one end user login to the web site with his own account , sometimes he can got content with other end user?s name in greeting messages, And there are set_cookie in response header once the user login. Besides, the confused page always has cache-control: no_cache, private set . The squid software release info is: Squid Cache: Version 2.5.12 configure options: --prefix=/usr/local/squid --enable-epoll --disable-ident-lookups --enable-async-io=160 --enable-storeio=ufs,aufs,diskd --enable-snmp --enable-cache-digests --enable-useragent-log --enable-referer-log --enable-kill-parent-hack --enable--internal-dns Does "collapsed_forwarding on" has some effect ? Can anybody give out a hand ? Thank you in advance. Adam Cheng
