Instead of a saved version, just store the hash of the saved version and do nothing if the hash is the same.

Instead of hashing the whole page, just hash the portion(s) of the content that you care about. That way different advertisements or updates to the nav links in the header/footer won't throw you off (unless you care about those sorts of changes too).
