Declaration
bool PropagateExceptions
Summary
                Determines whether exceptions in 
HttpServer.Handler, 
HttpServer.ErrorHandler and the response stream get
                propagated to the debugger. Setting this to 
true will cause exceptions to bring down the server.
Remarks
                    If false, all exceptions are handled. HttpException determines its own HTTP response
                    status code, all other exception types lead to 500 Internal Server Error. Use this setting in RELEASE
                    mode.
                    If true, only HttpException is handled. All other exceptions are left unhandled so
                    that the Visual Studio debugger is triggered when they occur, enabling debugging. Use this setting in
                    DEBUG mode only.
