+<b><font face="Arial, Helvetica, sans-serif"><font size=+2>Servlet
+Examples with Code</font></font></b>
+<p>This is a collection of examples which demonstrate some of the more
+frequently used parts of the Servlet API. Familiarity with the Java(tm)
+Programming Language is assumed.
+<p>These examples will only work when viewed via an http URL. They will
+not work if you are viewing these pages via a "file://..." URL. Please
+refer to the <i>README</i> file provide with this Tomcat release regarding
+how to configure and start the provided web server.
+<p>Wherever you see a form, enter some data and see how the servlet reacts.
+When playing with the Cookie and Session Examples, jump back to the Headers
+Example to see exactly what your browser is sending the server.
+<p>To navigate your way through the examples, the following icons will
+help:
+<br>
+<table BORDER=0 CELLSPACING=5 WIDTH="85%" >
+<tr VALIGN=TOP>
+<td WIDTH="30"><img SRC="images/execute.gif" ></td>
+
+<td>Execute the example</td>

+
+<tr VALIGN=TOP>
+<td WIDTH="30"><img SRC="images/return.gif" height=24 width=24></td>
+
+<td>Return to this screen</td>
+</tr>
+</table>
+
+<p>Tip: To see the cookie interactions with your browser, try turning on
+the "notify when setting a cookie" option in your browser preferences.
+This will let you see when a session is created and give some feedback
+when looking at the cookie demo.
