URL Redirection
URL redirection is a web technique that automatically forwards users from one URL to another, commonly used for website maintenance, URL shortening, or tracking purposes. It involves configuring a web server or application to respond to a request with an HTTP status code (like 301 or 302) that instructs the browser to load a different address. This process is essential for managing broken links, migrating sites, and improving user experience by directing traffic efficiently.
Developers should learn URL redirection to handle scenarios such as website rebranding, where old URLs need to point to new ones without breaking user access, or for implementing analytics and affiliate marketing by tracking clicks through redirects. It's crucial for SEO optimization, as proper use of permanent (301) and temporary (302) redirects preserves search engine rankings and ensures smooth user navigation during site updates or domain changes.
