iRule/http profile to change server side host header.

I found my issue, it was that the server was sending a 301 redirect to the client to force all clients to use that host header.

I used the following iRule to fix it up (from here)

    when HTTP_RESPONSE {
   do replace on Location header if we get one (e.g. http redirections) - not covered by stream profile
  if { [HTTP::header exists Location] } {
    regsub "remotedomain.com" [HTTP::header Location ] "localdomain.com" newlocation
    HTTP::header replace Location $newlocation
  }
}

Thanks for all the help guys 🙂
