It is common for client-server application to support HTTP Tunnelling in their connectivity scheme for the case where direct connection using plain socket connection is not applicable (e.g. pass firewalls to and from an organization). HTTP Tunnelling is based on Http protocol which by definition is a request response protocol where requests are initiated solely by the client and responses by the server. In order to achieve a persistent connection between the client and the server, the client needs to poll the server constantly in order to get updates. Existing polling methods are highly resource consuming or/and provide long response times. By using the Hybrid Polling method we minimize resource usage and gain better response time.
