Question

What is the correct JSON content type?

I've been messing around with JSON for some time, just pushing it out as text and it hasn't hurt anybody (that I know of), but I'd like to start doing things properly.

I have seen so many purported "standards" for the JSON content type:

application/json

application/x-javascript

text/javascript

text/x-javascript

text/x-json

But which one is correct, or best? I gather that there are security and browser support issues varying between them.

For JSON text:

application/json

The MIME media type for JSON text is application/json. The default encoding is UTF-8. (Source: RFC 4627).

For JSONP (runnable JavaScript) with callback:

application/javascript
