Java Servlets

User Authentication

A simple way is to use server security (later) and force the user to log in.
You can then do a
```
String name = req.getRemoteUser(); 
```
to get the name of the user.
It is easy to implement but has some problems:

It requires everyone to create account and log in.
There is no logout mechanism, just kill browser.
Cannot have more than one session at a time.
