This section provides an overview of the Web server-side scripting process flow. The Web server removes the script code and executes it.
Server-side scripting happens in step 4 as shown in the diagram below:
Step 1: The user enters a new Web page address or clicks a link that requires a new Web page from the Web server.
Step 2: The Web browser connects the Web server and sends a HTTP GET command with the path name
of the requested Web page.
Step 3: The Web server fetches the HTML document of the requested page or asks an application server
to generate the HTML document.
Step 4 - The Server-side scripting step: The Web server scans the HTML document for any server-side script code
embedded in the document. The Web server will remove the embedded script code and execute it.
When the Web server executes the embedded script code, it will provide many host objects representing
the server host environment. Through those host objects, server-side script code can easily access
the carrying HTML document, the server filesystem, any databases, and networked computers.
Usually, server-side script code will update the carrying HTML document with dynamic data resulted from its
computations.
At the end of the server-side script process step, the updated HTML document is ready to be sent
back the client - the Web browser.
