    // This horrible hack is needed for the 'use-credentials' tests because, on
    // response, if port 80 or 443 is the current port, it will not appear to
    // the browser as part of the origin string. Since the origin *string* is
    // used for CORS access control, instead of the origin itself, if there
    // isn't an exact string match, the check will fail. For example,
    // "http://example.com" would not match "http://example.com:80", because
    // they are not exact string matches, even though the origins are the same.
    //
    // Thus, we only want the Access-Control-Allow-Origin header to have
    // the port if it's not port 80 or 443, since the user agent will elide the
