Provides an application-wide implementation of the VaryByCustom property.
Assembly: System.Web (in System.Web.dll)
- Type: System.Web.HttpContext
An HttpContext object that contains information about the current Web request.
- Type: System.String
The custom string that specifies which cached response is used to respond to the current request.
You can override to add a new method for calculating custom vary-by values that are based on the current request. The implementation has to call the base class for custom values that it does not recognize. For more information, see How to: Cache Versions of a Page Using Custom Strings.
