redirect based on monitor status

Hi Nitass,

 

 

This works great and is really what I am working towards. I will expand the functionality to allow for a default behavior based on the monitor response allowing for a maintenance page and a technical issues type page.

 

 

The one additional issue I am struggling with now is that if I put all nodes in "disable mode" and then return a "maintenance" page I will interrupt existing sessions. I am wondering about trying to use something like LB:persist to determine if the client already has a session and if so allow them to age off normally but redirect any new sessions to the maintenance page. I tried to set a variable in a similar fashion to the is_disabled object and then make decision based on this value. However, I don't seem to be finding a session when I expect to using this function.

 

 

set client_session [LB::persist]

 

if { lindex $client_session 1 ] eq "0" }…

 

 

I tried this to see if I have a session

 

 

when HTTP_REQUEST {

 

set $client_session [ LB::persist ]

 

log local0. "The persistence entry is: $client_session and the key is [LB::persist key]"

 

}

 

 

But I don't see values for the key or value.

 

 

However, maybe there is a better way to try and determine if a client already has an active session?

 

 

Thanks.
