    I would like to work on an HTTP cache.
    You should think about the response object for the headers, Zend_Cache_Frontend_Page acts after the response is sent so it should be allright but perhaps an MVC plugin would be needed ?

    I think we should as well be able to controler the cache-control to prevent proxies from caching some pages, shouldn't we ?

    last thing : Zend_Cache_Frontend_Page has already got some support for such a HTTP cache system, see 'http_conditional' in it.
