How to direct the user to another virtual server if the existing virtual server is down by using irule?

Hi,

 

 

 

How to direct the user to another virtual server if the existing virtual server is down by using irule? If the existing virtual server has a valid fqdn name, for E.g www.serverA.com and the other virtual server doesn't have fqdn name but only the ip, can it be done? Please kindly show me the example.
application delivery
dev
devops
iRules

    Hi Thunderbird,

    In a typical situation here is the following 

    
when HTTP_REQUEST {
            if the members within the pool drop below 1 active member then process my next request
  if { [active_members http_pool] < 1 } {
                Send request to a new virtual server
                 virtual my_post_processing_server
       }
}

    This only works if the both the existing and the other virtual server is on the LTM

    I hope this helps
