Note: According to [http://support.microsoft.com/kb/318803 Microsoft], Windows XP considers TTL in its OS cache.

Firefox makes use of this cache, so TTL may already be covered indirectly in the Windows XP case. | Note: According to [http://support.microsoft.com/kb/318803 Microsoft], Windows XP considers TTL in its OS cache.
