Handling download method

Hi everybody,

I’m facing a problem which I’m sure many of you have already faced :

Is there a way to chose the way file downloads are being handled ? I mean you know that in Internet Explorer when you link to a file of which the type is unknown, the explorer will offer the choice either to download, either to open. When the mime type or the extension is known, it will automatically open the file.

That means, for instance for .swf files, they will automatically be played and not downloaded.

My question is : is there a way to force download and not playing ?

Thanks in advance.
