More a workaround than a solution, but...
Add a big label that says "Do not use your back button" in the header (or in each script producing the "dynamic" content
PLUS
build into your footer a link to something reasonable. Use standard .html if you're using a HERE for the footer; quote and escape VERY carefully if your footer is comprised of a bunch of

print "<p>something....</p>";
print "<p>something else...</p>";"
print "<p><a href='path/to/something/reasonable...'>something reasonab
+le</a></p>";
print "</body></html>";

where "something reasonable" is your home "page," the top "page" in the section from which the submit calls the cgi, etc.
