When used as an accessor (getter), the Item indexer returns true if a value for the specified parameter is found in the current parameters collection, or if the collection is set to vary by * (an asterisk), which indicates all parameters.

When used as a mutator (setter), the Item indexer sets the value for the parameter in the parameters collection that corresponds to the specified header to true. The value * can be specified, which indicates all parameters.

The following code example demonstrates how the Item indexer is accessed from the HttpCachePolicy object associated with an HttpResponse.
