The browser could do things other than viewing the file or downloading the file right away. It could also ask the user if they want to download the file. Or it could start downloading the file, detect a virus in it, and delete it right away. Note that this policy goes the other way. What should I do with this? If you have multiple formats of your file, and want to let the browser choose the best one it can view, then you could set up a system using the HTTP Accept header.

For instance, if you had both a ZIP and a RAR version of my-program , then you could make it so you link to just my-program and the browser chooses the version it likes best. If you want to force the browser to download a file even though the browser can probably view it on its own, see this question.

This will keep a "nice" URL myfile. To make this more robust you could add HTML5 feature detection and if it's not there then use window. Here's a different approach.

I prefer rather than to rely on browser support, or address this at the application layer, to use web server logic. If you are using Apache, and can put an. Of course, you could put this in httpd. The FilesMatch directive is just a regex so it could be set as granularly as you want, or you could add in other extensions.
