Internet Explorer Incompatabilities with WCCP and CE

[dmcquestion]

I have several users running Win2k and IE6 SP1 that are having problems with search engines and sites that require logins.

When they enter information into a search entry and click Search or Go, the page flickers (like it is refreshing) and does not present them any search results.

Other instances are when people try to log into subscription sites. They enter their credentials either to receive nothing or an error on the page.

When their local browser is configured to use the CE as a Proxy server, they do not have any of these problems. This leads me to believe the issue is with the WCCP interface and the CE's.

WCCP is running on the 6513.

Thanks

HI Danny,

first of all did you do a sniffertrace behind the CE and infront of one of those clients? Did you check if http traffic is handled properly by WCCP?

Btw what kind of Supervisor are you using and which ISO/ACNS release.

Cheers,

Joerg

Joerg,

Thanks for the reply.

Working on the traces now. Traces get complicated because the problem is not consistant and cannot be replicated on all computers. I'm also running several hundred people through the CE. It also seems like there is a new site each week.

6513 Hybrid mode

- Sup2 MSFC2/PFC2 v.12.1(19)E1a

CE510 v.5.1.3

Thanks

Hi Danny,

does this problem occur in case you are having hight load and bypassing occurs? Do you have a firewal between the CE and the internet? Is it possible that in case of bypassing either the IP-Adresses of the clients are not source-natted so that the return path from the Internet-server can not be found or that the Firewall drops internal HTTP traffic except the CE traffic?
