|
| 27 | Examples with Code</font></font></b>
|
| 28 | <p>This is a collection of examples which demonstrate some of the more
|
| 29 | frequently used parts of the Servlet API. Familiarity with the Java(tm)
|
| 30 | Programming Language is assumed.
|
| 31 | <p>These examples will only work when viewed via an http URL. They will
|
| 32 | not work if you are viewing these pages via a "file://..." URL. Please
|
| 33 | refer to the <i>README</i> file provide with this Tomcat release regarding
|
| 34 | how to configure and start the provided web server.
|
| 35 | <p>Wherever you see a form, enter some data and see how the servlet reacts.
|
| 36 | When playing with the Cookie and Session Examples, jump back to the Headers
|
| 37 | Example to see exactly what your browser is sending the server.
|
| 38 | <p>To navigate your way through the examples, the following icons will
|
| 39 | help:

|
| 61 | <p>Tip: To see the cookie interactions with your browser, try turning on
|
| 62 | the "notify when setting a cookie" option in your browser preferences.
|
| 63 | This will let you see when a session is created and give some feedback
|
| 64 | when looking at the cookie demo.
