BUSINESS OBJECT ATTACHMENTS AND EXPIRING URLS

摘要

A computer implemented method may include requesting details of an object and attachments associated with the object. The attachment details for each attachment may include an attachment name and an attachment ID. In response to a selection of an attachment associated with the object, a determination may be made as to whether a cache already includes the selected attachment. If the cache includes the selected attachment, the selected attachment may be retrieved from the attachment cache. If the cache does not include the selected attachment, the attachment may be downloaded using an attachment URL. The attachment URL may be requested and generated based on the attachment ID. The downloaded attachment may also be stored in the attachment cache.
