ASP.NET Web Handler file extension

Just as ASPX files can be compiled on the fly (just-in-time), so can handlers. Generic handlers have an extension of ASHX. They're equivalent to custom handlers written in C Sharp or Visual Basic.NET in that they contain classes that fully implement IHttpHandler. They're convenient in the same way ASPX files are convenient. You simply surf to them and they're compiled automatically.
