    Try this.

    when HTTP_REQUEST {
   if { [HTTP::host] contains ":" } {
      log local0. "[HTTP::host] becomes [getfield [HTTP::host] {:} 1]"
      HTTP::header replace Host [getfield [HTTP::host] {:} 1]
   }
}

What version are you running? Also, how were you testing? I just loaded that irule on a 14.1 box and I sent traffic through without a problem.

However, I couldn't get it to log an HTTP::host with the colon in it. I created a line to only log HTTP::host and it only puts the domain name, not the colon.

So, just curious which client you're using to test.
