US Patent 9769139 On-premises agent for mobile cloud service

Systems, devices, and methods are disclosed for an agent device within a company's network firewall to initiate an HTTP connection with a cloud-based gateway and then upgrade the connection to a WebSockets protocol in order to have an interactive session. Over this interactive session, a mobile device, which connects to the cloud-based intermediary, can request data from servers inside the company's firewalls. Because the firewall is traversed using HTTP protocols (with WebSockets), it can be as safe as letting employees browse the web from inside the company's network.
