Browser Cache Issue

[Former Member]

Hi Everybody,

We are using SAP Netweaver 7.3 Portal and integrated ABAP webdynpro applications by creating iviews in portal. SSO is configured and working fine.

Issue:-

Browser cache memory is not clearing  when we log off the respective user from the portal –  due to this applications behaves as same user even we log in with different user. If we manually clear the Browser cache, we are able to see the second user's application.

Any suggestions on how to resolve this issue will be really helpful.

Thanks,

Krishnaveni.

Tip:

If you start a new browser session, session cache will not be available.

For testing purpose, the -nomerge option is great!

Yes in a new session, the issue does not exist anymore. But that's not satisfying for our end users.

Your problem sounds familiar. In the browsers memory the ticket to the backend is still available after logoff, right?

After logging off from the portal, you will need to login to the java stack (portal). This will work with a different user. But when you go to a webdynpro abap application, the old user information is displayed (meaning a privacy risk!).

The only thing I can think of is closing the browser before logging in again. There is no function in javascript to clear the browser cache unfortunately.

In another reply I read something about two different backend systems. It is strange that the problem does not occur on the old system, meaning this isn't a browser issue...

Sounds like a SSO misconfiguration indeed.

Hi Noel,

Yes, you get it, it's exactly what's happening.

I've double checked the connection to the back-end, recreated a new one and it still appears. When I configure the connection to our old system it works well. Is there something to check in the back ends ?
