Server-Side Redirect

Server-side redirect is a web development technique where a web server automatically sends a user's browser from one URL to another, typically using HTTP status codes like 301 (Moved Permanently) or 302 (Found/Temporary Redirect). It occurs on the server before the response is sent to the client, unlike client-side redirects that use JavaScript or meta tags. This method is commonly used for URL management, site migrations, SEO optimization, and handling outdated or moved content.

Also known as: HTTP Redirect, URL Redirect, 301 Redirect, 302 Redirect, Server Redirect

Why learn Server-Side Redirect?

Developers should use server-side redirects when migrating websites to new domains or restructuring URLs to preserve search engine rankings and user experience, as 301 redirects pass link equity to the new URL. They are essential for handling broken links by redirecting users to relevant pages, improving site maintenance and reducing 404 errors. In web applications, redirects manage authentication flows, such as redirecting unauthenticated users to a login page, ensuring secure access control.
