Rewrite redirects to issuing host

Good point. I must have been distracted by the phone.

What I should have posted is this:

when HTTP_REQUEST {
  set host [HTTP::host];
  log LOCAL0.debug "URI=$host";
}
when HTTP_RESPONSE {
  if { [HTTP::status] starts_with "3" } {
      set location [HTTP::header "Location"];
      if { $location starts_with "http://" } {
          set temp [substr $location 7];
          if { $host equals [substr $temp 0 "/"] }{
              HTTP::header replace "Location" "https://$temp";
          }
      }
  }
}

Will [substr $temp 0 "/"] return the trailing "/"? If so, can anyone suggest an efficient way of dropping it?

Sorry to ask such simple, testable, questions. Unfortunately I don't have a test environment and will only have a short testing window when I put this in production.
