A redirect, in web development terms, is a way to send both users and search engines from one URL to another. It is a server-based function that automatically routes traffic to the correct page, helping to avoid the dreaded dead-ends of 404 error pages. Redirects are used for various reasons, including website restructuring, URL changes, or merging websites.
重定向出于多种原因很重要:
When a browser or search engine crawler requests a URL, the server checks if a redirect has been set up for that address. If a redirect is in place, the server returns a status code (such as 301 or 302) indicating the type of redirect, along with the new URL. The browser or crawler then automatically proceeds to the new location. This entire process is usually instantaneous, creating a seamless experience for the user.
