HttpRuntime Class
Provides a set of ASP.NET run-time services for the current application.
Assembly: System.Web (in System.Web.dll)
The HttpRuntime object is used at the beginning of the ASP.NET pipeline model that processes HTTP requests. The ProcessRequest method drives all subsequent ASP.NET Web processing.
Page developers can use the HttpRuntime class properties to find out information about the current application domain for diagnostic purposes, for example. Developers creating custom process pipeline or a custom hosting environment should call the ProcessRequest method from a class derived from the HttpWorkerRequest or SimpleWorkerRequest class.
The following example demonstrates how to get properties of the HttpRuntime class representing the current application domain and display them to the browser.
