01. Rot13

In order to be graded correctly for this homework, there are a few things to keep in mind. We'll be grading your web app by POSTing to your form and retrieving the text that has been encoded with ROT13. There are a few main issues you need to keep in mind in order for this to work:

• The textarea form element where the user inputs the text to encode must be named 'text'. In other words, you must have 'textarea name="text"' for us to post to.
• The form method must be POST, not GET.
• You must enter the full url into the supplied textbox above, including the path. For example, our example app is running at http://udacity-cs253.appspot.com/unit2/rot13, but if we instead only entered http://udacity-cs253.appspot.com/ then the grading script would not work.
• Don't forget to escape your output!
