(Doc ID 2314037.1)

Last updated on OCTOBER 05, 2017

Applies to:

Business Intelligence Suite Enterprise Edition - Version 11.1.1.7.0 to 11.1.1.7.170718 [Release 11g]
Information in this document applies to any platform.

Symptoms

We build an Oracle Http Server(OHS) in front of OBIEE.  And add configuration directives for handling static files in biinternal_vh.conf file. 

Example:

          "7.10.2 Configuring Oracle HTTP Server for Static File Caching"
           Configuration for Oracle HTTP Server is similar to configuration for Apache HTTP Server

 

According to the above documentation, OHS can also set the expiration date of static files.

However, after configuring the above setting, OBIEE login users can not be switched. The last login information unexpectedly saved in the browser's cache.

1. Access OBIEE with User A via OHS.

2. Open any catalog.

3. Sign out OBIEE.

4. Re-sign in as a different User B.

5. Access the catalog.

The catalog opened is not appropriate; logged in  User B has turned the User A who last logged in.
