What are the differences between

Response.AddHeader("Content-Disposition", "attachment;filename=somefile.ext")

and

Response.AddHeader("Content-Disposition", "inline;filename=somefile.ext")

I don't know the differences , because when I use one or another I always get a window prompt asking me to download the file for both of them. I read the specs, but it is clueless.

If it is inline, the browser should attempt to render it within the browser window. If it cannot, it will resort to an external program, prompting the user.

With attachment, it will immediately go to the user, and not try to load it in the browser, whether it can or not.
