Description Anne van Kesteren 2010-07-13 09:19:51 PDT
Per HTML5 http://www.whatwg.org/specs/web-apps/current-work/complete/web-messaging.html#dom-window-postmessage postMessage() should throw if targetOrigin contains a path component.

Anne, do you know if there is a good reason for this requirement? Ignoring unnecessary components seems cleaner in general.
Comment 3 Anne van Kesteren 2010-07-13 09:54:47 PDT
Authors might otherwise mistakenly believe they get more protection than they actually do. To me it seems cleaner to reject everything that is not an origin.
Comment 4 Alexey Proskuryakov 2010-07-13 10:14:08 PDT
In general, we strongly dislike raising exceptions where they weren't raised before, since that tends to transform minor/potential mistakes into serious breakage of functionality on existing pages.

The spec has changed.
Comment 6 Alexey Proskuryakov 2010-08-10 22:41:58 PDT
Thanks. This seems invalid per the new spec.
