'Warning: Page has Expired' In OAM-Protected Site After Clicking Back Button In Browser

(Doc ID 1326974.1)

Last updated on MARCH 08, 2017

Applies to:

COREid Access - Version: 10.1.4 to 10.1.4.3.0 - Release: 10g to
Information in this document applies to any platform.

Symptoms


Application access has been protected with Oracle Access Manager (OAM) 10g.

OAM SSO login to the application is working.

However if a user clicks the Back button in the browser they get 'Warning: Page has Expired.'

If the WebGate is removed from the application webserver configuration, the problem does not reproduce: the Back button does not cause any error and the previously accessed page is displayed.


Steps to reproduce

1. Access the application using a browser.
2. When prompted, submit valid OAM credentials.
3. The application page is displayed. Navigate around the application.
4. At any point, click the Back button. Error 'Warning: Page has Expired.' or 'Web Page Expired' is displayed.
