What does an xhr.status of 8 mean in IE8?

i just want to know what is the meaning of the xhr.status 8 and what is the possible cause of that (because my ajax failed and its the status that开发者_如何学JAVA is given to me).

Thanks

Edit : Just forget to specify that its only in IE, in Chrome or FireFox, it works (no error).

Maybe you can use a library like jQuery that does a pretty good job of abstracting away browser differences?

Same problem here. The only fix we found was that returning less json seemed to "fix" the problem. In our case this was acceptable, but I realize in most cases it's not.

Edit

Also should mention we are using YUI3. So it must not be library specific.
