Abstract

Examples of methods, systems, apparatus, and machine-readable storage media are provided to facilitate access and control of a remote desktop of a remote machine by a windows web browser of a client device through a web server without installing proprietary plug-ins or protocols on the client device. A web server may translate user input requests from a web browser into input calls compatible with a remote desktop display protocol. The web server may receive remote desktop drawing commands from the remote machine and translate the remote desktop drawing commands into web browser drawing updates compatible with the windows web browser. A web server may communicate with the windows web browser via HTTP and communicate with the remote machine via a remote desktop display protocol.
