HttpApplication.GetVaryByCustomString Method

Provides an application-wide implementation of the VaryByCustom property.

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

public virtual string GetVaryByCustomString (
	HttpContext context,
	string custom
)
public String GetVaryByCustomString (
	HttpContext context, 
	String custom
)
public function GetVaryByCustomString (
	context : HttpContext, 
	custom : String
) : String

Parameters

context

An HttpContext that contains information about the current Web request.

custom

The custom string that specifies which cached response is used to respond to the current request.

Return Value

If the value of custom is "browser", the browser's Type; otherwise, a null reference (Nothing in Visual Basic).

You can override GetVaryByCustomString to add a new method for calculating custom vary-by values 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.
