HTTP redirection is a technique used by web servers to redirect a client’s web browser from one URL to another. The process works by sending an HTTP response with a status code indicating that the requested page is being moved to a new location. The server then sends the URL of the new location to the client’s web browser, which then makes a new request for the page at the new location.
There are several types of HTTP redirects:
1. 301 redirect (Permanent): This type of redirect tells the client’s web browser that the requested page has permanently moved to a new location. Therefore, the browser should update its bookmarks and cache with the new URL. It also passes on the SEO value of the old URL to the new one.
1. 302 redirect (Temporary): This type of redirect tells the client’s web browser that the requested page has temporarily moved to a new location. The browser should only update its bookmarks and cache temporarily, as this may change back to the original URL in the future.
1. 307 redirect (Temporary): This is similar to 302 redirects but explicitly designed for HTTP/1.1 usage.
1. 308 redirect (Permanent): This is similar to 301 redirects but explicitly designed for HTTP/1.1 usage.
In summary, HTTP redirection involves the server sending an HTTP response to redirect the client’s web browser to a new URL. Redirection is useful when a web server changes the location of a web page or when it wants visitors to access a different URL than the one they initially requested.
