HttpResponse::AddCacheDependency Method

Associates a set of cache dependencies with the response to facilitate invalidation of the response if it is stored in the output cache and the specified dependencies change.

Namespace:  System.Web
Assembly:  System.Web (in System.Web.dll)

public:
void AddCacheDependency(
	... array<CacheDependency^>^ dependencies
)

Parameters

dependencies
Type: array<System.Web.Caching::CacheDependency>

A file, cache key, or CacheDependency to add to the list of application dependencies.

ExceptionCondition
ArgumentNullException

InvalidOperationException

This method was called too late in the cache processing pipeline, after the cached response was already created.

The AddCacheDependency method allows dependencies to be created between cached responses and a CacheDependency object.

The following example demonstrates how to create a cache dependency by using the AddCacheDependency method and a CacheDependency object.

No code example is currently available or this language may not be supported.
