IE 11 keep cache of json.

Hi, I'm a web developer of http://pre.labelby.me/

It's a RESTful web application.

User request via javascript then server response json object.

It works fine in firefox, chrome, safari, IE 7-10.

But It's not works in IE 11.

The problem that user can not login in IE 11 because IE 11 cached json file.

IE 11 cached current user object and always show the blank object.

I've spend a lot of time to solve this problem.

But I can't figured out yet.

I put some additional config to my apache configuration file, but it's not works.

BrowserMatch "MSIE 11.0;" IE11FOUND
BrowserMatch "Trident/7.0; rv:11.0" IE11FOUND
FileETag None
Header unset ETag env=IE11FOUND
Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"  env=IE11FOUND
Header set Pragma "no-cache" env=IE11FOUND
Header set Expires "Thu, 24 Feb 1983 02:50:00 GMT" env=IE11FOUND

Anyone have a solution for this problem?

Best Regards,
