Put another way:

Does tomcat

a) Assign a connection to a single thread and only use this thread for  
the connection until the connection is closed?


b) Assign a request to a thread, and return the thread back to a  
controlling thread on completion of the request?

My understanding is that the answer is 'A' except for the case of NIO  
and Tomcat 6.

BTW: The last thing I heard is that APR is still recommended for  
performance and stability over TC 6 NIO - or
do you have any newer info?
