Back port fix - Cookie path being set to empty string via getRequestContextPath forming invalid cookies in IE

When using the &lt;s:token &#47;&gt; tag in JSF, the <systemitem>javax.faces.ClientToken</systemitem> cookie that is created sometimes had an empty ("") path. The cookie was then not accepted in certain versions of <application>Windows Internet Explorer</application> and the following error message was returned: <screen> viewId: /myPage.xhtml - No client identifier provided. </screen> This update ensures that when an empty path is detected, "&#47;" is set as the cookie value. As a result, the cookie is accepted by all browsers and the above mentioned error message is no longer returned.
