What is an ASHX file?

An ASHX file is a webpage that is part of an ASP.NET web server application. It contains references to other pages hosted on the web server that are sent to the user's web browser. ASHX files are processed by the server's ASP.NET HTTP Handler when a client web browser requests the page.

More Information

Sometimes ASHX files are used for sending .PDF files to the user's browser, since the ASHX file has a reference to the PDF document. However, when the file is downloaded, the file extension is not renamed to ".pdf" and remains with the ".ashx" file extension. In this case, you can rename the file extension to ".pdf" and view it with Adobe Reader or another PDF viewer. You can also sometimes fix this problem by making sure that the web browser has the Adobe Reader plug-in installed. If installed, the PDF file may then open directly in the browser.

NOTE: Many ASHX pages have only a small amount of code, even as short as a single line. Page functions are written in the C# programming language.
