You can stop the browser reading a cached page by making all URIs unique.

You can do a quick-and-dirty by adding a random number to the URI's query string (as shown in test output below). 

[ ~/tmp ] $ perl -wle 'use strict; print join("", "fred.pl", "?dummy="
+, rand)'
fred.pl?dummy=0.67350901065311
[ ~/tmp ] $ perl -wle 'use strict; print join("", "fred.pl", "?dummy="
+, rand)'
fred.pl?dummy=0.079789433236332
[ ~/tmp ] $ perl -wle 'use strict; print join("", "fred.pl", "?dummy="
+, rand)'
fred.pl?dummy=0.844672383115725
[ ~/tmp ] $ perl -wle 'use strict; print join("", "fred.pl", "?dummy="
+, rand)'
fred.pl?dummy=0.288386549874307
[ ~/tmp ] $

To guarantee uniqueness, you'll need to replace rand with a call to something that will return a unique value - possibly a custom-built application which returns a unique value, reading the nextval from an Oracle sequence or something along those lines.
