Subject Re: Javascript mime type
Date Thu, 24 Jan 2013 21:25:54 GMT
According to this page:
and many others on the net, application/javascript is the correct answer, but not accepted
by MS IE ≤ 8. Which leaves us with text/javascript. But several places (including the above)
argues that leaving it empty is fine, and the most compatible. I have no strong opinions,
though, just that the present mime type definitely is wrong :)
