Session Persistence across devices

Hi all,

 

fairly new here and would like some help if possible, i have at the moment 2 IIS servers behind F5's the scenario i want is as follows:

 

user logs into website on one PC and user types some information.

 

user logs into another pc and needs to access page with information typed in already (This is managed in the application)

 

we just need to make sure when they access IIS from the second client machine they go through to the same server.

 

Hope that makes sense.

 

Thanks

  • It makes sense but really, the F5 has no way of knowing that second client is related to the first. Unless there is some unique information that we can inspect and use, this is not possible.

     

  • Yes, something in the URL would work just fine but wouldn't the user need to remember it?

     

  • There is a lot of interesting stuff that could be done with Universal Persistence, but some things to take into account in this particular case is if the servers are able to get the session ID or what you want to call it handled by other servers.

     

    Let me give an example - the user connects with the first PC and is loadbalanced to server 1 and is assigned the session ID 12345, once he's finished on the first PC he moves on to the second PC and connects and could possibly be loadbalanced to server 2. Once he logs in, server 2 must be able to retrieve session ID 12345 that was handled by server 1 and only then would he be sent back to server 1.

     

    If your application is able to handle that scenario, then it should be all right.
