How To Get Around the Holes In IE9 Beta's Implementation of Canvas 111
mudimba writes "Microsoft has made grand announcements about how great their implementation of the HTML5 canvas specification is. However, while I was porting a large HTML5 application to work with IE9 beta I found that there are some key features missing. Workarounds are provided where possible.

Do Apple systems not qualify as *nix anymore?

- since IE is the only browser to enforce XHR caching, every request needs a timestamp query parameter (something that no other browser does, and which is really stupid, altough easy to provide)
Or, you could use POST requests like you're supposed to. Any number of intermediary caches and load balancing tricks can play foul with GET requests, but POST is not allowed to be cached.
With jQuery this is as simple as using $.post() instead of $.get().

Hi there, thank you for the post. I just wanted to add a few observations on behalf of the Internet Explorer team.
Firstly, no browser offers a perfect implementation of the Canvas 2D API specification to date - we've documented and shared a few examples from our test suites here: http://samples.msdn.microsoft.com/ietestcenter/#html5Canvas [microsoft.com]
As has been well noted, the IE9 build tested was our beta.
Secondly, in response to the specific issues raised, Giorgio Sardo has posted a response on his blog here:

We'll update this entry over time.
Thanks for listening,
