| 24 | * Performs security handling of HTTP resources via a filter implementation. | |
| 25 | * | |
| 26 | * <P> | |
| 27 | * End users should <B>only</B> use this class to configure their HTTP security | |
| 28 | * configuration in an application context. They should <B>not</B> attempt to | |
| 29 | * invoke the <code>FilterSecurityInterceptor</code> except as a standard bean | |
| 30 | * registration in an application context. At runtime, this class will provide | |
| 31 | * services to web applications via the {@link SecurityEnforcementFilter}. | |
| 32 | * </p> | |
| 33 | * | |
| 34 | * <p> | |
| 35 | * The <code>ObjectDefinitionSource</code> required by this security | |
| 36 | * interceptor is of type {@link FilterInvocationDefinitionSource}. | |
| 37 | * </p> | |
| 38 | * | |
| 39 | * <P> | |
| 40 | * Refer to {@link AbstractSecurityInterceptor} for details on the workflow. | |
