The WebSphere Application Server security cookies must be set to HTTPOnly.

Web applications use cookies to track users across requests. These cookies, while typically not sensitive in themselves, connect you to your existing state on the back end system. If an intruder were to capture one of your cookies, they could potentially use the cookie to act as you. Important Web traffic should be encrypted using SSL. This includes important cookies.

In the case of WebSphere Application Server, the most important cookie is the LTPA cookie, and therefore it should be configured to be sent only over SSL.
