to change stored data, the request should use
 some other HTTP method.

 <p>
 The GET method should also be idempotent, meaning that it can be safely repeated. Sometimes making a method safe also
 makes it idempotent. For example, repeating queries is both safe and idempotent, but buying a product online or
 modifying data is neither safe nor idempotent.

 <p>
 If the request is incorrectly formatted, <code>doGet</code> returns an HTTP "Bad Request" message.</div>
