Gets a list of additional parameters from HTTP GET and POST requests by which caching is varied for the Web page to which this derived page adapter is attached.
Assembly: System.Web (in System.Web.dll)
Entities on the Web that cache Web pages cache multiple versions based on, among other factors, the request parameters. For example, a version for each store location within a retail chain for which a page might be generated would typically be cached based on the parameter name (for example, StoreID).
For specific browsers, it might be necessary to vary caching by GET or POST parameters in addition to the parameters that control target-independent caching. For example, it might be necessary to cache different versions of a page for different mobile phone service providers.Notes to Inheritors
When you inherit from the PageAdapter class, you can override the property to return a list of the additional GET or POST parameters to control target-specific caching. The base method returns null.
