Sharing a desktop screen is implemented on a Hypertext Transfer Protocol (HTTP) web server using variable interval GET and POST requests. Connection to a web server bypasses firewall or shared IP limitations. In the described HTTP/HTTPS only solution, an existing web server is used to allow one or more clients to view a remote computer's screen and control it (remoting). The web server can act as an intermediary to enable one computer to “take control” of a second computer by enabling the first computer (a client) to view the desktop session of the second computer (a host) and enable the first computer to act as master for input device input (e.g., keyboard input, mouse input, stylus input, etc.) for the second computer.
