Accoring to my understanding "Pragma: public" is wrong accoring to the 
RFC, and pretty much useless, as it should not be interpreted by any 
client or intermediary cache. (wrong+useless = bug, to me).
Thus TYPO3 should eigther drop it or replace it with a correct:
"Cache-control: public, max-age=..."

You might want to check http://redbot.org/?uri=http://typo3.org/ 
stating: "The Pragma header is being used in an undefined way".
