A Self-Contained Web Page

Now how can this be a good idea, Lewis?
Lewis' questions, which I must say is an interesting one, - can you generate a web page that can recreate itself?
In a quick conclusion, over lunch, it was decided that it is very possible using JAVA's API for handling files which could be used using JSP, however, it would be an absolute pain to maintain :-S

Anyway, I'm not going to go into detail about this, it was just an interesting question that I thought should be shared ;-)
