accesscontrolexception

问题 I am trying to access client's temp directory through my applet on my web project. When I run the applet by itself, it gets the tempdir with no problem.

问题 I know this is something usual, With the earlier versions of chrome I used to set "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --args --disable-web-security --user-data-dir in chrome shortcut tab to avoid 'Access-Control-Allow-Origin' errors. With the latest version, it seems like this fix is not working anymore. After installing the latest version 53.0.2785.89 m this is the error in console XMLHttpRequest cannot load https://example.org:15003/apps/services/preview/rr/common
