CGI method
The embedded web server supports the Common Gateway Interface (CGI) 1.1, a readily available means of handling dynamic data. The downside of CGI is that it's resource-heavy because it often involves an interpreted language.
SSI method
Server Side Includes (SSI) is a type of command language that can be embedded in HTML files.
Data server method
You can also handle dynamic HTML by using a data server process, ds. A data server lets multiple threads share data without regard for process boundaries. Since the embedded web server supports SSI, we've extended this support by adding the ability to talk to the data server.
