[TYPO3-english] Clear cache in backend module of an extension (TYPO3 4.5)

[Hauke Hain]

Hi Peter,

thanks for your reply.
Sadly this is no option. My extension is on every single page. In the 
backend module you can review new comments an unhide them or hide them 
again. On each action the page that contains the comment (it is stored 
directly on the page that displays the comment if not hidden, so I know 
which pid must be cleared) should be cleared. I do not want to have the 
extension not cached in order to see the result of the backend module action 
immediately.

Kind regards
Hauke
