I have HTML page on domain1 which includes javascript from domain2, it will create SWF component hosted on domain2. It is well knownswfupload component. The SWF component should start HTTP request to URL at domain2. It works in Internet Explorer and other browsers with no problem, but it does not work in application which is hosting Webbrowser control no matter what FEATURE_BROWSER_EMULATION settings I use (I've tried 8000, 9000, 10000, 11000 on IE 9,10,11). The same component works in hosted webbrowser if everything is at one domain.
Here is sample URL where it can be tested: http://rt1.noads.biz/demo/
After clicking the "Hello" button you are asked to choose any file from disk which is then uploaded in Internet Explorer, but after choosing the file in hosted web browser it just shows "Pending" in progress box instead of sending the file like in IE.
Any Idea how can I solve this? I'm having this problem for years since I've noticed this problem IE8 until today (IE11).
I've tried to implement IInternetSecurityManager with no success.
Thank you!
