Web Server DAT runs a web server in TouchDesigner. The Web Server DAT supports handling of HTTP requests and WebSocket connections. How client requests are handled is left up to the user via callbacks.

Currently only Basic authentication (ie. encoded username and password) is supported via a python method. Authentication will be in the HTTP request dictionary under the key 'Authorization'.

Ultimately, security is the complete responsibility of the user. It is up to the user to ensure that HTTP requests are properly authenticated, and any data storing usernames/passwords are encrypted or saved privately.

Currently doesn't support HTTPS.

Parameters - Web Server Page

Port port - The web server's connection port. Eg. If the port number is 9980, the web server can be connected to locally (via a web browser) at the address "localhost:9980".  

Start start - Starts the web server.  

Stop stop - Stops the web server.  

Callbacks DAT callbacks - A reference to a DAT with python callbacks. The Web Server DAT relies heavily on the Callbacks DAT, and in fact most functionality passes through the callbacks.

onHTTPRequest - Triggered when the web server receives an HTTP request. The request is a dictionary of HTTP headers. Similarly, response is a dictionary of response data such as status and reason. The response server must be returned from the callback. This response will be sent back to the client.

onWebSocketOpen - Triggered when a WebSocket connection is opened with a client. The client address is passed to the callback.

onWebSocketReceiveText - Triggered when the server's WebSocket connection receives text data from a client. The client that sent the text data is passed through to the callback.

onWebSocketReceiveBinary - Triggered when the server's WebSocket connection receives binary data from a client. The client that sent the binary data is passed through to the callback.

onServerStart - Triggered when the server starts.

onServerStop - Triggered when the server stops.

An Operator Family that manipulates text strings: multi-line text or tables. Multi-line text is often a command Script, but can be any multi-line text. Tables are rows and columns of cells, each containing a text string.

The generic thing that holds an Operator, and includes Flags (display, bypass, lock, render, immune) and its position/size in the network. Whether you "lay down an Operator" or "lay down an Node", you're doing the same thing.
