            <inSequence>
				   <cache timeout="30000" scope="per-host" hashGenerator="org.wso2.caching.digest.DOMHASHGenerator">
					   <implementation type="memory" maxSize="1"/>
				   </cache>
					<send>
						<endpoint name="secure">
							<address uri="http://10.100.1.228:9001/soap/SecureStockQuoteService">
