If you use local caching (by setting the cacheLocally property to true), the DistributorSender checks the file size and last modified time of items against the entries in a local cache of items that were sent to the remote servers. This cache component is called a RemoteServerCache.

To use this feature, create a RemoteServerCache component (of class atg.distributor.RemoteServerCache) for each DistributorSender or DistributorPool instance and set the remoteServerCache property of the DistributorSender or DistributorPool to point to it. The RemoteServerCache component might be configured like this:


The sizeLimit property sets the maximum number of entries in the cache.
