iRule required to persist client connections that get proxied from a single client.

Hi DevCentral,

 

I have an interesting scenario that I'm hoping someone has encountered before.

 

Basically I have one HTTPS VIP that serves both internal and external connections.

 

I am using source address persistence and this works fine for users connecting externally by way of a PC browser.

 

However, I have 300 BlackBerry users connecting to the same VIP using a custom built app. The only difference here is that all user connections are proxied by a BES server and consequently all connections go to one pool member because of source address persistence.

 

Question? How do I achieve load-balancing and persist client connections?

 

Any pointers would be greatly appreciated.

 

Thanks,

 

Nathan

    Have you tried using cookie persistence?

      Hi DevCentral Guru's, I've just decrypted the SSL data from both BlackBerry and PC client to find a common attribute to enable persistence for. So all I require is a simple iRule to persist on ASPSESSIONID Anyone out there have a simple iRule that they wouldn't mind sharing? Thanks, Nathan

      Everything you need should be here, including your iRule: http://support.f5.com/kb/en-us/solutions/public/7000/300/sol7392.html
