NimbostratusDirect traffic to specific pool member
I have a situation where I have a pool with three members. I need a way to open three tabs in a web browser and access each of the three members each in a different browser tab. Is there a way to write an irule that will allow me to somehow specify the pool member in the uri and then keep a persistent connection to that node? Since the source IP address would be the same on all three browser tabs, I can't create an irule based on source address. It would have to be some other method but I don't know what it would be.
- The_BhattmanHi Runner,
There is a code share that Hoolio posted up that might just do the trick

Keep in mind that this is something you might want to keep out from the public. From a security perspective you do not want someone to discover that they can specifically pick up the backend system via URI
I hope this helps

Hi Runner,
Here is an example iRule you could try:

Aaron- hoolioYeah, what Bhattman said :)

runner_1355Thanks! I will try this tonight during our outage window.- hoolioI'd try testing this iRule on a test virtual server before putting it on a production virtual server. And As Bhattman suggested, you might want to limit by client IP/network, who can select their pool member directly.
