Redirection, originally meaning “to change direction,” is the automatic transfer of visitors to a web page to another web page, also known as HTTP redirection or URL redirection.
It is also called HTTP redirect or URL redirect.
2 types of redirection methods
There are two methods used: one is to redirect the user as soon as the web page is accessed, and the other is to redirect the user a few seconds later after displaying a message informing the user that the web page has been moved.
The method of transferring the data at the time of access is instantaneous and does not require any effort on the part of the user, but on the other hand, it is difficult for the user to notice the fact that the page has been moved, and therefore, the page may become inaccessible once the transfer is completed. The method of notifying users of the relocation and then transferring the data requires more waiting time than the above method, but allows users to be aware of the fact that the data has been moved.
Therefore, automatic forwarding is usually used for temporary moves and evacuations, while forwarding after announcement is used for permanent moves.
Shortened URLs also use the redirection function.
Shortened URLs are also implemented using a function that redirects the user to the page where the URL was published.
However, this is different from 301 redirects, so if you want to use 301 redirects, we recommend using .htaccess.
