Invoked upon an exception. This handler can stop the propagation of an exception e.g by creating a "clean" HTML response instead of showing the stack trace. In this case the unified response provided as a parameter must be filled.

Parameters:

aRequestScope - Current request scope incl. http response object. Never null.

t - The thrown exception. Never null.

Returns:

EContinue.CONTINUE if further exception handlers should be invoked, EContinue.BREAK if the exception was finally handled.
