Cache consumers should call this method only if DefaultCacheCapabilities.VirtualDirectory is supported by this cache (by checking the DefaultCacheCapabilities property.

GetItemVirtualDirectoryUrl returns a URI to any item currently stored in the cache. Obtaining a URI to a cache item can be useful in a Web application if the client code is JavaScript for example.

LEADTOOLS Documents Web Service classes uses this method to quickly access the data of an item to speed up access and updating the data if the value contain large amount of data such as an image file. If the cache implementation does not support virtual directory access, then the web service gets the whole item using a regular "get" operation and then streams it back to the client.
