Creating a Custom HttpHandler in Windows SharePoint

ASP.NET programming supports the creation of custom HttpHandler components, which provide a flexible and efficient way to process requests that don't return standard HTML-based pages. For example, HttpHandler components are great for situations in which you want to return simple text, XML, or binary data to the user.
