That's actually quite a difficult question. What you're basically asking is what is the mime-type of a javascript file. The answer is that it is officially 'application/javascript'. However, this has only recently been published as part of the standards.

I am aware of RFC 4329[1], but that is only "Informational", and it dates back to April 2006. Is there any other standards document specifying "application/javascript"?

Until just a few years ago, there was no agreed mime-type for javascript files; this is why you'll see text/javascript, application/x-javascript, etc. being used all over the place. The HTML4, html5 and xhtml (1 and 1.1) speccs all expect a text/javascript mimetype when using javascript. In the end... it doesn't really matter that much. You could technically send a mime-type of text/plain and it would still work just fine. This is simply because most browsers don't trust the headers sent but tend to take a peek into the first packets sent, and decide what it contains based on that. So... I'd personally use application/javascript since that's the official mime-type. But it doesn't really matter that much which one you use ;)

Unless you have to support old IE. AFAIK, IE 8 ignores scripts with an "application/javascript" MIME type. [1] <http://www.rfc-editor.org/rfc/rfc4329.txt> --Christoph M. Becker
