    OK, this is what i did which did the trick:

    Added the maintenance server as a node on the LTM Create a pool called maintenance_pool and added my maintenance page server to it. Created an irule called maintenace_page with the following in it:

    when HTTP_REQUEST {
    if {[active_members [LB::server pool]] < 1 }  {
        pool maintenance_pool
    }
 }

    Applied the rule to the Virtual servers needed. Voila. Works like a charm!

    I really did not want to host the maintenance page on the LTM as we often change those pages and it is easier for the DEVs to do it directly on the server itself.

    Thanks again for your help OTS02.

I do not know of a way to do that. Once you redirect, you have no more control over their connection. May I ask why you want to do that? BTW, you can accomplish the redirect from the http profile, by placing 'maint.xyz.com' in the fallback host window.
