The 'Pragma' header you use is from HTTP/1.0. Most caches, including browser cache, by now use HTTP/1.1, where cache control is achieved differently. You should use 'Cache-Control' headers (although it never hurts to also use 'Pragma' headers, in case you encounter an older HTTP/1.0 cache). For more information you can look at the HTTP/1.1 RFC at: ftp://ftp.isi.edu/in-notes/rfc2616.txt and search for the text 'Cache-Control'.
