How to write redirect a URL with all except one

Would this work? Have a default pool for xyz.com attached to the VS and another pool called abc_app (for example) with the abc app server in it.

when HTTP_REQUEST { 
   switch -glob [string tolower [HTTP::uri]]  { 
      "/abcredirect*" { 
        HTTP::uri "/" 
        } 
      "/abc*" {
        pool abc_app
        }
    } 
} 

Hope this helps,
