Multiple redirects on one VIP

If all of the domains resolve to the ViP that the iRule is configured on, you probably want to limit the iRule by checking the requested path first. If the path equals "/", then check the requested host header value. You can add this check to the top of the iRule:

 
  when HTTP_REQUEST {  
  
      Log a debug line for every request  
     log local0. "[IP::client_addr]:[TCP::client_port]: New request to [HTTP::host][HTTP::uri]"  
  
      Check if requested path is / 
     if {[HTTP::path eq "/"}{ 
  
         Redirect based on the host header value  
        switch [HTTP::host] {  
           "*1*" {  
    ... 
 

And you would need to remove the HTTP::redirect from the default case.
