title: Connections pooling REST calls made from Bluemix nodejs apps in to DataCenter services via Datapower
body: <p>Hi We have a UI component deployed to Bluemix on Noedjs which makes REST service calls (JSON/XML) to services deployed in Data-center. These calls will go through the IBM Data Power gateway as a security proxy.<br>
  Data Power establishes an HTTPS Mutual Authentication connection (using certs that are exchanged offline) to the caller. 
  Although this method is secure it is time consuming to set up and if this connection is in setup for each service request it will create a slow response for the end user.
  To optimize response time we are looking for any solution which can pool connections between nodejs app deployed on Bluemix and DataPower security proxy. Any one has any experience in this area?</p>
