Applies to: desktop apps only

The UseCacheCondition property gets or sets a value from the FpcCacheAction enumerated type that specifies the conditions under which an object should be retrieved from the cache. The possible types of cache usage behavior are:

If there is a valid (unexpired) version of the object in the cache, the cached object should be used. Otherwise, a new version of the object should be obtained from the Internet.
If any version of the object is found in the cache, the cached object should be used. Otherwise, the object should be obtained from the Internet.
If any version of the object is found in the cache, the cached object should be used. Otherwise, an error page should be returned, and no attempt should be made to obtain the object from the Internet.

This property is read/write.
