So is there a separate file for each session that get created and then 
destroyed? Is the file method the default method? Which of the two is 
used more? What are the pros and cons of each? Am I correct in assuming 
that the file method require the file to be parsed for each page load? 
At what point are you going to see a degradation in performance with 
either method?
