    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]

Hello Anthony.

That's a common issue with HTTP::header command when you use it with quotes. Just do this to avoid the error

set new_header "[substr [HTTP::host] 0 ":"]"
HTTP::header replace Host $new_header
