SSI method

Server Side Includes (SSI) is a type of command language that can be embedded in HTML files.

With SSI, you can add dynamic content to your HTML. Slinger uses the PATH and CMD_INT environment variables to provide information to the SSI command, exec. Using dynamic HTML, clients can offer interactive realtime features on their web pages.

Clients can create dynamic HTML by placing SSI tokens in the HTML code of their web pages. The SSI token contains a command that's handled by Slinger. While transmitting the HTML code, Slinger replaces a token with HTML data, based on the tag contained in the SSI token.

For example, the embedded server can:

• execute utilities at user-defined points in an HTML document (the output of these utilities can be optionally inserted into the document)
• insert contents of other HTML files at a user-defined point
• handle conditional statements (e.g., if, break, goto), so you can define what parts of an HTML file are transmitted

For Slinger to process SSI tokens, the HTML file must have .shtml as its file extension.

You can use SSI tags to interact with a data server.
