org.silverpeas.core.security.SecurableRequestCache

public class SecurableRequestCache
extends Object

A common tool to handled securable implementation with a request cache.

Indeed, the computing about secured access can be costly about performances and using a request cache could be interesting when access authorization is computed several times for a same entity into the context of a same request.
