What is redirect? Meaning. Type of redirects.

There are several types of URL redirects that a webmaster can implement for a URL that is temporarily or permanently unavailable. There are five types of redirects: 301, 302, 303, 307, and 308.
The 301 redirect indicates that the original content of the page has been permanently moved to another URL.
The 302 redirect indicates that the content has been temporarily moved.
Both 301 and 302 redirects are implemented by the web server.
There is also an on-page technique for redirecting a URL called meta refresh redirect, but meta refresh redirect causes more latency and is therefore considered a poor user experience.
