P3P Policy

The Platform for Privacy Preferences Project (P3P)

, is a protocol allowing websites to declare their

intended use of information they collect about browsing users. The system P3P policy plug-in allows

Joomla to send a customized string of P3P policy tags in the HTTP header. This is needed for the

sessions to work properly7with certain browsers, i.e. Internet Explorer 6 and 7.

Cache

This module provides page caching. You can conﬁgure whether you would like7 to use the client's

browser for caching pages.

Debug

conﬁgure the parameters to determine which information to display.
