A service controller on a computing device can be configured to redirect serial output over a network using HTTP. For example, the service controller can be configured with a web server that can receive the serial output and stream the serial output to a web browser over an HTTP connection. In some implementations, the HTTP connection can be a WebSocket connection, as defined by the HTML5 specification. In some implementations, a proxy server can be configured with a web server that can receive serial over LAN (SOL) output from multiple servers and stream the SOL to a web browser on a client device.
