Rules fallback - 4.5 PTF-05 Build 25

Ok, first time posting so please forgive.

 

 

We have a http pool with 3 servers in it.

 

 

The company wants to purchase some forum software, but it is expensive so they only want to place it on one server in the pool.

 

 

Using rules I am told I can do persistence based upon a uri and send all traffic that matches http://servera/forum to hostA.

 

 

The question the users are now asking, if the server with the forum software (hostA) is down, can the BigIP box recognize this and reroute the request to another server within the pool that has a page that says "Our forum software is currently unavailable".

 

 

Thanks in advance for your help

    Yes. Read the Pools - Priority-based member activation section of your Reference Guide. For example:

     

    pool forum_pool {

     

    min_active_members 1

     

    member 10.4.4.1:http priority 2

     

    member 10.4.4.2:http priority 1

     

    }

     

     

    The high priority member references your forum server and the other member references a server which serves the Forum Off-line page.
