302 redirects is a
temporary redirect status which is also a web server function. As per the
function, an URL is directed to a new one through the temporary 302 redirect.
It is basically a way by which the HTTP redirects the client to a new location
for a temporary period. For instance if a client is visiting site and the
content have been moved to page b for the time being then this is 302 redirect.
The move is not permanent and therefore for future purpose the user should go
to page an only. The 302 redirect is performed directly by the browser and the
user doesn’t have to do anything. He can enter the original URL of the site on
the address bar and the browser would take him to the temporary address on its
own.
The move is
temporary until the original URL is reestablished. This is why the user should
keep checking the original webpage time and again to see if it has been
reestablished. In this case the content would again be shifted to the original
site and would no longer be available at the redirected site. Apart from 302
redirects, other kinds of URL redirects are also there and can be implemented
by the different sites.
