Christopher Tubbs commented on ACCUMULO-4676:
---------------------------------------------
I preserved this change as I merged in ACCUMULO-3005. We can probably drop
sessions entirely now, but until that is done, I've kept this change with the
session handler.

> Currently, the JSESSIONID cookie in Monitor UI doesn't have HTTPOnly flags
> set. If the HttpOnly attribute is set on a cookie, then the cookie's value
> cannot be read or set by client-side JavaScript. This measure can prevent
> certain client-side attacks, such as cross-site scripting, from trivially
> capturing the cookie's value via an injected script. A malicious client-side
> code can access the JSESSIONID and hijack active sessions to gain
> unauthorized access to the application.
