Please could somebody list the browsers and versions for which the Content-Type: Multipart/X-Mixed-Replace is supported for creating an application based on comet principles. I have read conflicting accounts of its support in Chrome and Internet Explorer - although some reports mention its inclusion in IE 10.

A follow-up question is, how stable is this technology to build real-time applications? I ask because Wikipedia currently lists this Content-Type as experimental.

Thanks in advance!

The page you link to also answers your question. It is supported in FireFox, Chrome and Safari, but not in IE or in Safari on the iPhone. The page doesn't say anything about IE 10, but since it isn't officially released yet, that makes sense.

According to MSDN, though, IE 10 does seem to support Comet streaming.

Apart from IE, it has been around for years (since 1995 actually) and should be very stable. The reason why it is marked experimental, is that it isn't declared an official standard yet.

Apparently Google Analytics already uses this technology and I think they wouldn't if it wasn't stable.

  • Thanks for your reply. However, I specifically did say browsers and versions, in fact the main thing I'm after is the specific versions of browsers which support the `Content-Type: Multipart/X-Mixed-Replace`. Also if Google Analytics are using this technology I would like to see a reference please! :) – Jasdeep Khalsa Dec 23 '12 at 16:56
  • Well, as you can see, 'Google Analytics' is a link to the page that made the claim. About versions: it was introduced in [Netscape already](http://web.archive.org/web/19981203153836/fishcam.netscape.com/assist/net_sites/pushpull.html), apparently even in [Netscape 1.0](http://www.abiglime.com/webmaster/articles/cgi/032498.htm) meaning that FireFox at least supports it since its first version. Remember that most browsers alive today didn't even exist when this content type was 'invented'. – GolezTrol Dec 23 '12 at 18:34
  • Apparently, it was added to [Webkit (Chrome, Safari) by the end of 2005](http://www.stefanseiz.com/archives/2003/06/safari_and_content-type_multipartx-mixed-replace.html). – GolezTrol Dec 23 '12 at 18:42
