Impact

Some content could be not displayed on a page accessed through Portal Access.

Conditions

This can occur with web applications that use heavy javascript including javascript across iFrames.

Workaround

iRule workaround specific to a web application

Fix Information

Now iFrame with empty origin inherits origin value from parent window being accessed via Portal Access in the same manner as all browsers do.
