There’s different ways to do redirects depending on the hosting company you are using. The most common way is with an .htaccess file if your host is using Apache web server and supports that.
RW8 has a built-in htaccess editor inside the publishing settings.
The htaccess file supports varieties of ways to redirect a URL’s depending on what and where you want to redirect and what return code if any you want issued.
Your post title indicates you want a temporary(302) redirect. The obscure example you gave makes it difficult to give you a best answer but the simplest type of redirect with Apache htaccess would be a single line alias redirect.
Redirect 302 /path/to/old/file/old.html /path/to/new/file/new.html
