| <FONT color="green">037</FONT> * Note that while the default value for the "contextRelative" flag is off,<a name="line.37"></a> |

| <FONT color="green">040</FONT> * with the flag on, they are considered relative to the web application root.<a name="line.40"></a> |
| <FONT color="green">041</FONT> * Since most web apps will never know or care what their context path actually<a name="line.41"></a> |
| <FONT color="green">042</FONT> * is, they are much better off setting this flag to true, and submitting paths<a name="line.42"></a> |
