Oracle webcache and Oracle eBS 11i....

I have installe Oracle webcache 10.1.2.3.0 to act as a reverse proxy server for our Oracle eBS environments.

After installing the webcache, I used note 380486.1 to configure webcache for our R12 environments. Now, we can use the webcache url to enter the R12 application.

For our 11i environments I used note 306653.1

Using the webcache I am able to login the 11i application, but when starting a forms session I see the following error

'You don't have permission to access /pls//fnd_icx_launch.launch on this server.'

What is going on here ???
