Yes, the script that I'm using for if-modified-since eliminates the 
Cache-Control header for the results of browse actions.  I also don't 
know if no-store serves any purpose in the context of PmWiki--I just

because I wanted to get caching issues out of the picture as much as I
could in the earlier stages of PmWiki development and distribution.
