Definition - What does 302 Redirect mean?
Techopedia explains 302 Redirect
302 redirects may be on-domain redirects, where a URL is replaced with another from the same domain, or off-domain redirects, which actually take the browser from one domain to another. In many cases, a 302 redirect can return a simpler and cleaner URL for users. Along with the utility of this method, there are also concerns about security, specifically the risk of URL hijacking, where unauthorized hackers can redirect users.
Different search engines and other technologies have their own specific strategies for using 302 redirects. The IT community looks at how these standards are changing in ways that will serve Web users better while providing competitive security on the Internet.
