The Add method adds only providers that are specified in the configuration for a Web site. Therefore, it does not add the ASP.NET default provider for the in-memory output cache.
This collection is read-only. It is populated one time based on the providers that are specified in configuration. After the collection is populated, you cannot modify the set of available providers.
