What is the use of having iframe tag in gwt host html page? Is any specific reasons behind this?
When i’m using iframe with ssl enabled it’s giving me an popup window(get messages stating that there is un-secure content in the page.). Happening only in ie.. How to avoid this ?
Update: the problem was because of the Flash used in the page (FlasTag setting the code base to http://download.macromedia.com). More details here.
__gwt_historyFrame is used to store/retrive history tokens (make back/forward button work correctly). If you don’t embed an iframe, GWT history mechanism won’t work.
Update by Tomas Broyer:
As pointent out here, iframe is not the only possible cause.
