The user control is not associated with a BasePartialCachingControl and is not cacheable.

By default, these strings correspond to a query string value sent with the GET method or to a parameter sent using the POST method. When the VaryByParams property is set to multiple parameters, the output cache contains a different version of the requested document for each specified parameter. Possible values include "none", "*", and any valid query string or POST parameter name.
