Thanks for the replies John & Jens, The app can run in http/https, the user can then configure the app to consume various resources, for example rss feeds, web services - in this instance the feed resources contained images which were then loaded over http.
The issue was/is that IE throws a javascript network error when the image has it's url set - this is only reproducible in IE + GWT + SSL - mimicking the GWT code in vanilla Javascript + IE +SSL doesn't throw any errors, so I don't *think* it's a certificate/ssl/browser thing. Your right we should be using history management - but the inclusion of an iframe shouldn't cause a runtime error. Again this only occurs in IE + GWT + SSL.
