No there is not.
The closest you can get is to send them a 4xx forbidden page when this

the page is displaying badly and actually needs a refresh.

recommended settigns are:
   acl PURGE method PURGE
   http_access allow localhost PURGE
   http_access deny PURGE

Needs to be above any http_access which
