Persistent iRule

Hello,

 

 

I have an application that opens a new session everytime you click on a link within the application so the cookie persistent load balancing method does not work properly for this setup. I configured a simple IP load balance persistent profile for it which works ok. However, this is causing a problem with multiple people coming from a proxy.

 

 

Is there any parameter that I can look at with an iRule that can evenly distribute the load? Can it see anything before the proxy or differentiate the sessions some how?

 

 

I am running 9.4.6 on 3600 platforms.

 

 

Thanks in advance!

    So if the back end server starts a new session when you click on a link(meaning there will be no cookie inserted in the new session when the GET request comes in for that new link) how does the F5 correlate that new session with the previous session and persist to the same server based on the UIE?

     

     

    I think I missed that command in the example.

     

     

    Is that based on the 'persist uie []' or the 'persist lookup' command in the first link?

     

     

    If so, any recommendation on a particular parameter in the payload, URI or Path? I guess I am gonna have to get this info from the App engineer to determine what to look for? Or very possible I am not understanding how the UIE works.

     

     

    Thanks
