IHttpHandler.ProcessRequest Method (HttpContext)

 

Enables processing of HTTP Web requests by a custom HttpHandler that implements the IHttpHandler interface.

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

Sub ProcessRequest (
	context As HttpContext
)

Parameters

context
Type: System.Web.HttpContext

An HttpContext object that provides references to the intrinsic server objects (for example, Request, Response, Session, and Server) used to service HTTP requests.

Place your custom HttpHandler code in the ProcessRequest virtual method, as shown in the following example.

The following code example writes four lines of text to the HTTP output stream in response to a client request for a page named handler.aspx. All requests for handler.aspx are serviced by the MyHttpHandler class in the namespace HandlerExample contained in the assembly HandlerTest.dll.

' Name this Visual Basic file HandlerTest.vb and compile it with the
' command line: vbc /target:library /r:System.Web.dll HandlerTest.vb.
' Copy HandlerTest.dll to your \bin directory.
Imports System.Web

            context.Response.Write("<p>Your Browser:</p>")
            context.Response.Write("Type: " & context.Request.Browser.Type & "<br>")
            context.Response.Write("Version: " & context.Request.Browser.Version)
        End Sub
