Determines when the cached item will be destroyed - Read/Write.
object.Persistence [= value]
The Persistence property syntax has the following parts:
| Part | Description |
|---|---|
| object | A valid WebCacheItem object |
| value | A PersistenceTypes value. |
The settings for value are:
| Setting | Description |
|---|---|
| ddPermanent | 1 - Cached item will stay alive forever. The item has to be destroyed using an explicit WebCache.Remove call. |
| ddTimeout | 2 - Cached item will remain in the cache for a time period specified by the end user via the WebCacheItem's Timeout property. A possible usage scenario is setting the Timeout property to the SessionTimeout value under IIS. |
| ddAccessedOnce | 3 - Cached item is destroyed immediately after the client accesses the data one time |
