Default
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.
