<h1>How To Work With WebGoat</h1>
<p>
Welcome to a short introduction of WebGoat.<br>
Here you will learn how to use WebGoat and additional tools for the lessons.<br><br>
<b>The interface of WebGoat</b><br><br>
</p>
<h1>Environment Information</h1>
<p>
WebGoat uses Apache Tomcat as server. It is setup to run on localhost. This
configuration is for single user. If you want to use WebGoat in a laboratory or in
class you might need to change the setup. Please refer to the Tomcat Configuration
in the Introduction section.</p>
<h2>The Interface Of WebGoat</h2>

1. Here you see all Categories of Lessons in WebGoat. Click on the Categories to see all Lessons in it.<br>
2. This link will give you the technical background to solve the lesson.<br>
3. Do you need some help to find the solution? Here you will find useful hints.<br>
4. Here you will find a complete solution of the selected lesson.<br>
5. If you want to restart a lesson you can use this link.<br><br><br>
<b>Solve the Lesson</b><br><br>
Always read first the lessons plan. Then try to solve the lesson and if necessary, use the hints. If you cannot solve the lesson using the hints, you may watch the solution. Here every step is explained.<br><br><br>
<b>Read and edit Parameters</b><br><br>
To read and edit Parameters you need a proxy to intercept the HTTP request. Here we use WebScarab. More informations to WebScarab you will get in the Chapter "Useful Tools".

<h2>Solve The Lesson</h2>

Always read first the lessons plan. Then try to solve the lesson and if necessary,
use the hints. If you cannot solve the lesson using the hints, you may watch the
solution. Here every step is explained.</p>
<h2>Read And Edit Parameters</h2>
<p>
To read and edit Parameters you need a proxy to intercept the HTTP request.
Here we use WebScarab. More informations to WebScarab you will get in the
Chapter "Useful Tools".
After installing WebScarab and making a proxy on localhost we can start.<br><br>
<img src="/WebGoat/images/introduction/HowToUse_1.jpg"><br><br>
We have to select "intercept request" in the tab "Intercept". If we send a new HTTP request now, we get a new WebScarab window.<br><br>
<img src="/WebGoat/images/introduction/HowToUse_2.jpg"><br><br>
Here we can read and edit the sent parameter. After "Accept changes" the request will be sent to the server.
<br><br><br>
<b>Read and edit Cookies</b><br><br>
</p>
<h2>Read And Edit Cookies</h2>
<p>
Often it is not only necessary to change the value of parameters but to change the value of cookies. We use again WebScarab and intercept the request as explained in the last topic.<br><br>
<img src="/WebGoat/images/introduction/HowToUse_3.jpg"><br><br>
We again get the new window on sending a HTTP request. On the screenshot you see where we can find cookies and how to edit the values of them.

<h1>Create A WebGoat Lesson</h1>
<p>
Adding lessons to WebGoat is very easy. If you have an idea that would be suitable<br>
for a new lesson, follow these few simple instructions to implement it:<br><br>
* Download the source code from <a href="http://code.google.com/p/webgoat/">here.</a><br><br>
* Setup framework: follow the simple instructions in "HOW TO create the WebGoat workspace.txt" that comes with the project.<br><br>
* You need to add two files for each new lesson: <br>
&nbsp;&nbsp;- YourLesson.java to org.owasp.webgoat.lessons<br>
&nbsp;&nbsp;- YourLesson.html to WebContent/lesson_plans<br><br>
&nbsp;&nbsp;- YourLesson.html to WebContent/lesson_plans</p>
<!-- Stop Instructions -->
<br>
<p><b>General Goal(s):</b> </p>
The user should be able to learn how to add a new lesson.
