ZF-9600: Zend_Cache_Frontend_Capture does not automatically disable front controller output buffering; it should
Presently, in order to use the cache, one must disable Zend_App's own output buffering in the following fashion (also for using Zend_Cache_Page):
resources.frontController.params.disableOutputBuffering = true
However, this is not documented. After talking with MWOP it was his suggestion that the cache automatically do this on behalf of the user.
