You don't need that for dynamic images, XML, or binary files. Image Output. Is there any performance advantage or change to using ASHX files?

These files are less complex and they do not involve as many events. They are more streamlined and involve less code, and this is an advantage. As you can imagine, firing more than ten events each time a request is handled is a fair amount more expensive than only firing one event.

Therefore, there will be some performance advantage to using ASHX files where possible. IsReusable I do not know precisely what the IsReusable property does. Much of the supporting code is not in the ASHX file itself. But My reading indicates it can improve performance and decrease memory pressure by not repeatedly destroying the handler.

Choose handlers. Here I want to propose some guidelines about when to choose custom handlers and when to prefer ASPX web form pages. Handlers are better for binary data, and web forms are best for rapid development. Control trees. In the ASP.
