Do all browsers support PHP's $_SERVER['HTTP_X_REQUESTED_WITH']?

Question

Do you know of any browsers or times where $_SERVER['HTTP_X_REQUESTED_WITH'] would not work?

It's not "php's" HTTP_X_REQUESTED_WITH. – VolkerK Aug 09 '09 at 13:36 — VolkerK, Aug 09 '09 at 13:36

Sending of a X-Requested-With header really depends on the Ajax library used. I checked out Prototype, jQuery, Mootools and YUI and they all set it.

I don't think this particular header is the issue here - the only case where I've seen this is with Ajax requests, and even in those cases it's usually a custom header set by the JavaScript library in question.

Do all browsers support setting custom request headers for XMLHttpRequest? As far as I know, yes, it works in all modern browsers.
