Hi,
we’ve some “request canceled”-problems in tests with IE8. We use wpt version 2.8 with non-virtualized agents. Same tests in Firefox doesn’t have canceled requests.
Example: http://www.webpagetest.org/result/121129_W3_8FM/1/details/
For test-instances of the shop we have even much more canceled requests (see attached waterfall). What could be the reason for cancellation?
Regards, Nils
Usually cancellations are caused by this: http://blogs.msdn.com/b/ieinternals/archive/2011/07/18/optimal-html-head-ordering-to-avoid-parser-restarts-redownloads-and-improve-performance.aspx
I’ve never seen it that pervasive or happening to tracking beacons but I guess it’s possible if those are loading in an iFrame. It is very much an IE-specific behavior so I wouldn’t expect to see it in Firefox or Chrome.
