Questions:
I am delivering a JS response from a PHP file. When setting the Content-Type header which value should I use, application/javascript or text/javascript?
What’s the difference between the two?
How to&Answers:
According to the IANA Registered MIME media type list, JS has two registered MIME types; the obsolete text/javascript and the now official application/javascript.
Thus, use application/javascript.
Answer：
From Wikipedia on Internet Media Types
application/javascript:JavaScript; Defined in RFC 4329 but not accepted in IE 8 or earlier
There is also the deprecated text/javascript (which IE will probably not choke on).
