## Version 4.6.0

 *  Fix: Follow HTTP 307 and 308 redirects on methods other than GET and POST. We're reluctant to
    change OkHttp's behavior in handling common HTTP status codes, but this fix is overdue! The new
    behavior is now consistent with [RFC 7231][rfc_7231_647], which is newer than OkHttp itself.
    If you want this update with the old behavior use [this interceptor][legacy_interceptor].

  var i = 0

      if (i == 16) result.writeByte(':'.code)
    } else {
      if (i > 0) result.writeByte(':'.code)
      val group = address[i] and 0xff shl 8 or (address[i + 1] and 0xff)
      result.writeHexadecimalUnsignedLong(group.toLong())
