iRule code for OWA and Symantec Enterprise Vault

Hi all, please forgive yet another post on Enterprise Vault and F5's. Been searching for a solution for a while with no joy so any assistance will be appreciated.

 

We currently deploy our Exchange environment through TMG servers which we are replacing with F5 devices. For external OWA access through an APM/LTM we need archived emails from our Enterprise Vault servers to be made available to the end users. I'm aware we need to add code to our HTTPS redirect iRule. Can anyone suggest what this iRule code should look like?

 

iRule novice I'm afraid :-(

 

Thanks
