+<p>
+Cookies without <code>HttpOnly</code> attribute are accessible to JavaScript running in the same origin. In case of
+Cross-Site Scripting (XSS) vulnerability the cookie can be stolen by malicious script.
+</p>
+</overview>
+
+<recommendation>
+<p>
+Protect sensitive cookies, such as related to authentication, by setting <code>HttpOnly</code> to <code>true</code> to make
+them not accessible to JavaScript.

+</recommendation>
+
+<example>
+
+<p>
+In the following example the default <code>HttpOnly</code> value is <code>false</code>.
