About This Topic

Server-side programming means running code on a web server to build responses dynamically, such as rendering HTML templates or processing form submissions. MCQs compare server-side rendering with client-side rendering and ask about template engines like EJS, Pug or Handlebars. You should know how the server parses request bodies, handles file uploads, sets cookies and maintains sessions, and what CGI, PHP and application servers do. Concurrency models are a recurring theme, contrasting thread-per-request servers with Node.js's event-driven, non-blocking I/O. Reverse proxies such as Nginx, WebSockets for real-time communication, and server-side request forgery (SSRF) also appear.

Below are 30 practice questions from a pool of 210 Server-Side Programming MCQs, one of 17 topics in Web Development. Each shows the correct answer with an explanation; when you are ready, take a timed quiz to test recall under exam conditions.
