Stale comment authentication values in IE

Users have complained about IE 6 displaying cached/stale numbers in the "math question".
Max Rudman suggests the following fix.

I don't know if this is limited to 6 but this definitely seems to be
IE-specific problem. The issue is that the include generated by
CommentAuthenticatorServlet is getting cached. So, when you post a
comment and the page gets redisplayed, IE includes cached HTML
fragment which has the previous math question. The solution is to
output cache-defeating headers in CommentAuthenticatiorServlet.doGet
() method:

response.addHeader("Pragma", "no-cache");
response.addHeader("Cache-Control", "no-cache");
response.addHeader("Expires", "-1");
