Hi, I have this quite weird problem with Squid working with Cisco 6509 Core Switch as WCCP transparent proxy. Some pages doesn't open on clients (or it takes ages to open). There is a Polish web portal which many people visit - www.onet.pl - this is the one of very few which suffers. When I open the page in FF it says: "Waiting for csr.onet.pl…" I can not see any record in access.log regarding csr.onet.pl then (why?). If I type "csr.onet.pl" into FF there is no record in access.log either (why??). When I do "w3m www.onet.pl" on the client it opens OK. Also "w3m csr.onet.pl" generates record in access.log: 1267439340.585 71 10.10.0.243 TCP_MISS/404 629 GET http://csr.onet.pl/ - DIRECT/213.180.146.120 text/html The most weird thing is that some clients open the page, some not: Safari on Mac OS X works OK FF on Mac OS X works OK Opera doesn't work on Linux nor Mac OS X Everything works great on every browser when I use explicit proxy (manually config proxy in browser). What I have is: Debian 5 Lenny (current updates) Squid Cache: Version 2.7.STABLE3 WCCPv2: wccp2_router 10.10.4.26 wccp2_forwarding_method 1 wccp2_return_method 1 wccp2_service standard 0 GRE tunnel at Debian -A PREROUTING -i gre0 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 3128 Cisco: IOS (tm) c6sup2_rp Software (c6sup2_rp-PSV-M), Version 12.1(27b)E3, RELEASE SOFTWARE (fc1) #show ip wccp web-cache detail WCCP Cache-Engine information: Web Cache ID: 10.10.4.4 Protocol Version: 2.0 State: Usable Redirection: GRE Packet Return: GRE Assignment: HASH Initial Hash Info: 00000000000000000000000000000000 00000000000000000000000000000000 Assigned Hash Info: FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF Hash Allotment: 256 (100.00%) Packets Redirected: 4164751 Connect Time: 09:43:21 Best Regards, Mike
