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!
In the term of SEO , 301 and 302 both are good it is depend on situation,
If only one version can be returned (i.e., the other redirects to it), that’s great! This behavior is beneficial because it reduces duplicate content. In the particular case of redirects to trailing slash URLs, our search results will likely show the version of the URL with the 200 response code (most often the trailing slash URL) -- regardless of whether the redirect was a 301 or 302.
