A storage proxy includes a cache resource. A processor is configured to receive read and write requests sent from an initiator to a target over a first proxy path. The processor invalidates the cache lines when the read and write requests are redirected over a second direct path between the initiator and the target or when some other event indicates the data in the cache lines may no longer be consistent with corresponding data in the target. The processor identifies addresses for at least some of the cache lines that were previously valid and reloads the data for the identified addresses from the target back into some the cache lines when the read and write requests are redirected back over the first proxy path or when consistency can resumed between the data in the cache lines and corresponding data in the target.
