ObjectCacheSessionHandler should avoid pointless writes in write()
Closed, ResolvedPublic


Until PHP 5.6, write() is called regardless of whether anything changed. We should detect changes and no-op if there's nothing to do. This is useful for multi-DC sessions to cut writes down to a trickle (nearly all in the hot DC).
