internet explorer - Font-awesome disappears after refresh for all ie browsers ie11,ie10,ie9

Question

I know it seems this question has been asked before, but the solutions I've found are for IE8 only.

We are using Font Awesome 4.1.0 and Bootstrap v3.0.3 in our project. If we load the page for the very first time all the icons render properly. When we reload page in Internet Explorer using Ctrl + R, they disappear.

This issue is occurring for all IE versions we've tested, including IE11.

Answer 1

So the issue was on IE with https in all the request one header related to no-catch pragma was coming extra and that header was causing issue in loading font.

following code was added to context.xml file to fix this issue.

<Context>
    <Valve className="org.apache.catalina.authenticator.BasicAuthenticator" 7
        disableProxyCaching="false" />
</Context>

And that context.xml file was kept in our ROOT folder.
