the problem is: where does this users get the links without cHash from?
 
a workaround would be to check if a value for cHash is given from GPvars in
your extension before outputting any content. If no cHash exists -> no
output. So all users who type in urls by hand will see a white page or - if
a chash was typed in by hand - caching will be disabled by TYPO3 because
incoming and calculated cHash doesn't match.
