problem for static bypass

[david.lung]

I have a software problem on Content Engine (CE)ACNS 5.1.9b7 . In our

environment, we enable transparent cache service on CE and WCCPv2 on

router. On CE, we disable dynamic bypass feature and use static bypass list instead of dynamic bypass .its CPU is not high (around 8%).

When the connections are established, the client's packets are intercepted by CE and CE will surf the web page on behalf of the client IP. However, we find some client's packets can byass through the WCCP router and reach the web server directly. In the view of the web server, they will receive from some packets from client IP and some from CE IP for the same connection. This cause the web application cannot

work properly.

If the Content Engine is used in transparent caching environment, it always sends the packets that it does not understand to the router. This way is ensured that connections started before the CE was put in service, don't get broken. This effects also packets sent by client station after the connection is closed for any reason (retransmission, RST) and causes unexpected traffic sending out, or logged at the firewall.
