Hi again,

sorry, I just now see my first question is answered on the main web  
server documentation entry page (one really should not skip the  
overview pages and directly jump in somewhere ...!)
So I see my guess was at least quite correct :-;
So now my question would become which is better to use: the stateful  
version, storing to the database when necessary, or the stateless one,  
providing a stuffer?

Sorry again for the lapse & thanks,
