Not seen above iRule. But you can try something like this. 

when CLIENT_ACCEPTED {
  if { ([llength [active_members -list poolname]] < 1) and ([HTTP::path] eq "/favicon.ico")  } {
  HTTP::respond 301 Location "https://www.website.com/other/favicon.ico"
         }
}

    Hi Samir,

     

    Thanks for the quick response but unfortunately the iRule doesn't work. I received the following error when attempting to use it.

     

    01070151:3: Rule [/Common/ASID103898_pool_redirect] error: /Common/ASID103898_pool_redirect:3: error: [command is not valid in current event context (CLIENT_ACCEPTED)][HTTP::respond 301 Location "https://www.website.com/other/favicon.ico"]

    /Common/ASID103898_pool_redirect:2: error: [command is not valid in current event context (CLIENT_ACCEPTED)][HTTP::path]

     

    Could I please also clarify that there's an LTM policy that utilises a lot of pools on this VS, the iRule has to be specific to the current session, so that it doesn't impact the other VS connections.

     

    Thanks!
