LB on hash key with onloading and offloading
Hi,
I'm a complete newbie for F5, so I hope my question makes sense. We would like to load balance on a pre-hashed cookie value. The value is hashed using a proprietary (i.e. Oracle) hashing...

Hi Brian,
Can you describe in this forum the logic of what you want the LTM to accomplish.
For example:
1. Client goes to VIP
2. VIP selects server based on default load balancing configuration and forwards the request to server
3. Server then responds and assigns a pre-hashed cookie value
4. Client receives the cookie and responds back with the same cookie value
5. F5 then checks the pre-hashed cookie value and then based on the value sends the information to a specific server?
etc.
The short answer is that it is possible for the iRule to read cookie values, store in a variable where it can be evaluated to process it into the states you defined. However, not exactly sure how the last 2 states (starting/Stopping) can be accomplished without learning the logic of what you want the flow to look like
