Don’t mistaken this with the 301 redirect. Basically a 302 redirect is a temporary redirect.
In other words, if your content is temporarily moved to a new page or site, you can use a 302 redirect to tell the search engines to redirect your visitors to this new location.
This is to ensure that they do not pass the link juice and the anchor text over to this new place because sooner or later, your original page or site will resume back to its original establishment.
