// 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
// ports in those cases.
