Class PrimeNumbers


public class PrimeNumbers
extends HttpServlet

Servlet that processes a request to generate n prime numbers, each with at least m digits. It performs the calculations in a low-priority background thread, returning only the results it has found so far. If these results are not complete, it sends a Refresh header instructing the browser to ask for new results a little while later. It also maintains a list of a small number of previously calculated prime lists to return immediately to anyone who supplies the same n and m as a recent completed computation.
