How to redirect if less than x nodes are avail

That would be a relatively simple iRule:

 

 

when HTTP_REQUEST {
  if { [active_members http_pool] < X } {
    reject
  }
}

 

 

X would be changed to the minimum number of active members, of course.

 

 

This code is almost identical to the example in the Wiki on the active_members page: Click here

 

 

HTH,
