This application is an introduction to a few of the core ideas involved in building a web application. Most importantly:

• Routing, i.e., the relationship between the URL you visit in your browser and the code your web application runs.
• Query strings as a way for the user to pass dynamic information from the browser to the web application.
• Dynamically generating HTML documents to send back to the browser
