The CacheTime property is an Integer value that specifies the
number of seconds provider information and model information should remain
cached by the control.
The control may cache information such as provider capabilities,
available models and model metadata to reduce unnecessary network requests
and improve performance. Cached information may be reused until the cache
interval expires.
In most cases, the default cache interval is appropriate and this
property does not need to be changed. Reducing the cache time may increase
network activity and provider requests, while increasing the cache time
may delay visibility of changes such as newly available models or updated
provider capabilities.
Setting this property to zero disables caching and forces the control
to request updated provider and model information whenever needed.
