| 38 | * When constructed on the client via {@link | |
| 39 | * org.acegisecurity.context.rmi.ContextPropagatingRemoteInvocationFactory}, | |
| 40 | * the contents of the <code>SecurityContext</code> are stored inside the | |
| 41 | * object. The object is then passed to the server that is processing the | |
| 42 | * remote invocation. Upon the server invoking the remote invocation, it will | |
| 43 | * retrieve the passed contents of the <code>SecurityContextHolder</code> and | |
| 44 | * set them to the server-side <code>SecurityContextHolder</code> whilst the | |
| 45 | * target object is invoked. When the target invocation has been completed, | |
| 46 | * the server-side <code>SecurityContextHolder</code> will be reset to a new | |
| 47 | * instance of <code>SecurityContextImpl</code>. | |
