[Zope] detect pressed refresh button in browser

[Dirk Datzert]

Hi Oliver,

I have ran into a RAMCacheManager problem:

users changed content of a pages which is displayed on other pages
where content is cached. 

The normal user action would be pressing refresh button.

I want to invalided the relevant cache content object on a refresh.

Regards,
Dirk

In which way sessions could help me ?
