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.

Recently users of my website complained about the lack of support to IE6\7.
Is there an offline tool to test if a page-HTML isn't compatible with a specif browser and where is the problem?
Where can I find a list of things I need to be aware of in order to support IE6?
Update: The problems the users describe are in the UI, <Div>are not in the right places and that kind of problems, not JavaScript issues.
I can't force the users to upgrade theirs browsers.
IE6 is an ancient browser. Tell people who complain about lack of support that it's no longer supported and they should upgrade.
There is no "syntax checking" tool to find all incompatibilities, because the problems are not in syntax but how it's interpreted. There is no way around visual testing I'm afraid.
Here are some interesting SO questions on the topic:
One fix for all IE6 problems

Running Internet Explorer 6, Internet Explorer 7, and Internet Explorer 8 on the same machine
IE tester is useful for testing across version of internet explorer. It may not tell you what is wrong but you will at least be able to see / verify what users are reporting.

I have some offer about this for you :
Try to use Jquery more,because Jquery is compatible with most browsers
there are 3 useful addons for Mozilla : Firebug , Web Developer , IE tab
IE 9 has a developer windows that you can change your page standard into IE 8 or 7
Use syntax liek this :
<link rel="stylesheet" type="text/css" href="Styles/ie-fix.css" />
maybe this is useful dude for you :)
If your users are complaining about IE6, you should give support to IE, thats theory. BUT, if possible do as google has been doing for years, if the user is using IE6/7 or lower show some links to download newer browsers and tell them that their browser is too old.
You can use a seperate stylesheet for IE.
There is a third party software named Utilu. Utilu IE Collection contains multiple standalone versions of the browser Internet Explorer, which can be used at the same time. It has more than 10 versions of IE. But its used for viewing the web pages. This software also has firefox and chrome collections.
Like the title says I'm just wondering the current support for canvas.toDataUrl? I have it working in Firefox 4 but haven't really tried it in any other browers. When I look it up on Google most of the results are pretty scattered as some are from a year ago. It says its only supported with webkit nightly builds. (which I assume now are the actual releases)
I'd also like to know the support for mobile devices as well.
I personally prefer using caniuse.com for finding out the current browser support. Caniuse covers various major releases of each browser, as well as some mobile browsers. However, I always recommend that with anything mission critical, you test in all browsers just to be on the safe side.
If you take a look again at caniuse.com you will see that the support tables are all color-coded and they tell you whether a browser fully-supports, partially-supports, does not support, or does not support (but a polyfill exists). The canvas.toDataUrl, property would fall under the category of "basic support", which shows that the canvas api (or rather the current working draft for it) is fully supported in all major browsers, and there is a polyfill available for IE.
So while it doesn't go into great detail about the specific properties browsers support, it stands to reason if a browser "fully-supports" the basic canvas API, you can safely assume that includes toDataUrl. Once again, if you dont want to leave things to chance, or if you for some reason do not trust caniuse.com, your best bet is to build a test-suite and personally test your app against all browsers.
Actually it's currently broken in the webkit nightly build, a minor security bug I found a couple days ago:
http://code.google.com/p/chromium/issues/detail?id=91016
But in general in the stable release of Chrome it works just fine. In IE9 it works just fine too.
Can someone tell me how to use HTML5's speech recognition support with IE9 (relevant web page explaining how would be great)? Or does only Google Chrome 11 beta have that support?
-- roschler
It's a WebKit experiment, it's not yet been accepted into any W3C or WHATWG spec, there is currently no such thing as 'HTML5 Speech Recognition' just a proposal. If it does get accepted, and Microsoft continue to follow their site ready policy, then you can probably expect to see it in either IE11 or IE12.
Does BlackBerry OS 6's HTML5 implementation support websockets?
There was a page on BB's developer portal where the supported tags were listed, but I can't seem to find it anymore.
Anyone know if websockets are supported?
Thanks
After some testing and research throughout the web, I've come to conclude that websockets are not yet supported on BlackBerry devices.
Although some tests might indicate they're supported, the implementation is just a stub. Too bad.
The list of supported tags can be found here.
Try Mondernizr on your phone to check whether WebSockets are supported.
I think the only browser supporting WebSockets is iOS Safari 4.2.
Planning to use HTML5 in a big project, I need to make an exact timeline for future changes.
Is there any source to tell me when a particular feature of HTML5 will be ready? Is there a roadmap for HTML5 support for each particular web engine?
Just for some more details, I’m working on a social/video sharing site. I want to use new features from CSS3 to HTML5 to JavaScript. Don’t tell me “You can use <video> right now” because I know that!!
Also consider the fact that it takes some time for all people to update their browsers to new ones
Yes:
When can I use...
I need to make an exact time-line for future changes.
So you want Microsoft, Apple, Mozilla, Opera and Google to tell you exactly when they’ll be done adding features to their browsers? Just e-mail them, I’m sure they’ll get right on that :)
Naw, interesting question. I don’t think any browser manufacturers commit to implementing specific features particularly far into the future. In the case of HTML5, the spec itself says that the spec won’t be done until there are two agreeing implementations, so it’s very much a matter of “wait until an implementation ships”.
In the case of WebKit and Firefox, they‘re open-source projects, which I imagine makes it more difficult to commit to far-future dates. Then again, I seem to remember Microsoft being a bit late with Vista, so it’s probably difficult to commit to dates for closed-source projects as well. If you could edit your question with the exact date when your social video sharing site will be finished, that’d be a good start.
A quick Google turns up:
Internet Explorer
Microsoft have got IE 9 in beta. This page claims to be some sort of roadmap: http://microsoft-journal.spaces.live.com/blog/cns!A33F7112F6C1D499!878.entry
There’s also their Internet Explorer Blog
Firefox
Mozilla announced their plans for 3.6 here: https://wiki.mozilla.org/Firefox/Namoroka
Couldn’t find a similar document for 4 (which was originally announced as 3.7), but robertc pointed to this document which details the HTML5 (and CSS3) features added in Firefox 4: https://developer.mozilla.org/en/Firefox_4_for_developers
WebKit (Safari and Chrome)
“Apple doesn’t comment on future products” — http://trac.webkit.org/wiki/FAQ
But the WebKit team do have a blog, Surfin’ Safari
Opera
Folks were apparently clamouring for a roadmap last year: http://dev.opera.com/forums/topic/294965
It all depends on your target audience. If it is South Korean middle aged businessmen with 99% IE6 penetration, you're not likely to be able to use anything fancy any time soon. If it's art directors working in advertising, you can probably already use whatever bleeding edge feature Webkit has implemented.
