Server-side scripting is a web development technique that enables a website to deliver dynamic content, creating a unique experience for each user. With server-side scripting, the originating server processes a script before the page is sent to the user's web browser. This allows the website to generate custom content for each user, based on their specific requests and other variables such as their location, device type, access rights, etc.

Server-side web languages include PHP, Python, Ruby, C#, and JavaScript.
