Some article I read once said that it means jumping (from one URI to another), but I detected this \"302\" even when there was actually no jumping at all!
EXAMPLE:- Although it is not very common that we find ourselves in need of a 302 redirect, this option can be very useful in some cases. These are the most frequent cases:
A redirect 302 is a code that tells visitors of a specific URL that the page has been moved temporarily, directing them directly to the new location.
In other words, redirect 302 is activated when Google robots or other search engines request to load a specific page. At that moment, thanks to this redirection, the server returns an automatic response indicating a new URL.
In this way errors and annoyances are avoided both to search engines and users, guaranteeing smooth navigation.
