How do I force a file to download instead of displaying inline in IE, Firefox and other browsers?

You can force a file to download by using a combination of the <cfheader> and <cfcontent> tags. We'll use a jpg for this example. It will work for any file type however.

<cfheader name="content-disposition" value="attachment;filename=example.jpg">
<cfcontent type="image/jpeg" file="C:\files\example.jpg">

Note the use of filename in the <cfheader> tag. This allows you to give another name to the file being downloaded.

You can also change the value of cfheader to inline;filename= if you want to make sure its displayed in the browser, so you can easily do things like view or download options for the user using the same code.

You might want to add quotes around the filename in order for filenames with spaces to work in FireFox.

filename="example.jpg" filename="my very spacy document.doc"
