HttpHandlerAction Class

Configures an HttpHandlersSection configuration section. This class cannot be inherited.

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

public sealed class HttpHandlerAction : ConfigurationElement

The HttpHandlerAction class provides a way to programmatically access and modify the add element of the httpHandlers configuration section.

This type is part of a group that includes the HttpHandlerActionCollection and the HttpHandlersSection types.


The HttpHandlerAction can read and write information from and to the related section of the configuration file according to the section property AllowDefinition whose value is Everywhere.

ASP.NET searches for the handler assembly DLL in the application's private \bin directory first, and then it searches in the system assembly cache.

The following code example shows how to use the HttpModuleAction type.

// Get the handlers.
System.Web.Configuration.HttpHandlerActionCollection httpHandlers = httpHandlersSection.Handlers;

The following configuration excerpt shows how to specify values declaratively for the httpHandlers section.

  <add path="Calculator.custom"
    type="Samples.Aspnet.SystemWebConfiguration.Calculator, CalculatorHandler"
    verb="GET" validate="false" />
