In HTTP, Prompt to Save and XML File Rather Then Render

Question

In a Web Application I am creating, users can backup their data locally. The backup data is an XML file. At the moment, most browsers try to display this file. What should I change in the HTTP response to suggest to a user-agent that the file should instead be saved?

Answer 1

You need a Content-Disposition header:

Content-Disposition: attachment; filename=my_backup.xml

Answer 2

You need to use content disposition like:

AppendHeader("Content-Disposition", "filename=MyExportedFile.xml");

This will give you a save prompt rather than attempt to render to screen
