HTTP Redirects
URL redirection also known as URL forwarding
is a technique to give more than one URL address to a page, a form, a whole website, or a web application. HTTP has a special kind of response, called a HTTP redirect, for this operation.
eg; What you see when twitter.com redirects to x.com is referred to in backend/software engineering as a URL redirection.
Redirects accomplish numerous goals:
Temporary redirects during site maintenance or downtime
Permanent redirects to preserve existing links/bookmarks after changing the site's URLs, progress pages when uploading a file, etc.
In HTTP, redirection is triggered by a server sending a special redirect response to a request. Redirect responses have status codes that start with 3, and a Location header holding the URL to redirect to.
Alternative way of specifying redirections
HTTP redirects aren't the only way to define redirections. There are two others:
Why It Matters;
For SEO: A 301 tells search engines to transfer SEO rankings, eg from
twitter.comtox.com.For User Experience: Ensures users who type the old domain still reach the new site.
For Brand Migration: Reflects Twitter's rebranding to "X".
