Concurrent Caching

The BlackBerry® Attachment Service maintains the cache for 25 minutes or until a new request exceeds the cache limit for that conversion process. If the cache limit is exceeded, the BlackBerry Attachment Service deletes the document with the oldest time stamp from the cache.

To prevent multiple requests for the same attachment from using the first cached copy of the attachment DOM in a conversion process, you can set this drop-down list to Disabled.
