iRule to redirect to "down"page on other VS

I am trying to find a way to redirect an https virtual server/pool to a different virtual server/pool if all node members are unavailable. The profile setup to a fallback host does not work. When I change the profile on the VS from "none" to "down" where I have a downtime page identified in the fallback host (http://down.domain.com) the site locks up and fails with a page unavailable. I was hoping a simple iRule would perform the same purpose. Any ideas?

    Here's what I use:

    
when LB_FAILED { 
 switch [LB::server pool] { 
  default { 
   HTTP::redirect http://maint.mydomain.com
  } 
 } 
}

    I have tried something similar. The problem is that if I assign a profile - even the default http profile - the site quits working. After about 5 minutes it comes back with the standard Microsoft page cannot be displayed error.

     

     

    I have a number of other sites on this switch without the problem. The only difference is that this is a https site (not redirected).
