301 is a permanent redirect, and 302 is a temporary redirect. The browser is allowed to cache the 301 but 302 means it has to hit our system every time. assuming that we want to minimize the load on our system, 301 is the right decision. Imagine creating URL shortening service for a big company, we try to get as less hit to our servers by the ...

The only difference between 307 and 302 is that 307 guarantees that the method and the body will not be changed when the redirected request is made. With 302, some old clients were incorrectly changing the method to GET: the behavior with non-GET methods and 302 is then unpredictable on the Web, whereas the behavior with 307 is predictable.

An overview of 301, 302 and 307. The RFC 7231, the current reference for semantics and content of the HTTP/1.1 protocol, defines the 301 (Moved Permanently) and 302 (Found) status code, that allows the request method to be changed from POST to GET.

Note that 302 was intended to have the behavior of 307, but most browsers implemented it as the behavior of 303 (both of which didn't exist back then). Therefore, those two new codes were introduced to replace 302. The difference between 301 and 303: 301: The document is moved. Future requests should use the new url.

A 302 redirect means that the page was temporarily moved, while a 301 means that it was permanently moved. 301s are good for SEO value, while 302s aren't because 301s instruct clients to forget the value of the original URL, while the 302 keeps the value of the original and can thus potentially reduce the value by creating two, logically-distinct URLs that each produce the same content (search ...

Feb 7, 2013 · It's correct. Actually 307 is variation of the more common 302 redirect. 301 Moved Permanently This and all future requests should be directed to the given URI. 307 Temporary Redirect (since HTTP/1.1) In this case, the request should be repeated with another URI; however, future requests should still use the original URI.

Sep 23, 2016 · I don't know about the 302, but I tested the 301 on some browsers today, here the results: SCENARIO: user clicks link on domainX that points to domainA. domainA does a 301 redirect to domainB. IE8 referer when landing on domainB is: domainX (even when using InPrivate browsing and even when user opens link in new tab)

Jan 2, 2012 · By saying "temporary move" a 302 tells search engines to keep the old domain or page indexed, but it would be desireable for them to index the new location. People use 302 redirects in an effort to circumvent the Google aging delay. This workaround might have worked at some point, but it is not a current best practice. Ref: 301 Vs 302 Redirects

Jan 26, 2012 · Are there any actual caching or performance implications of choosing 301 vs 303/307. I don't think so. For GET requests, is there any reason to pick 303 vs 307? 303 has semantics different than 307. If the requested resource is "somewhere else", 303 is not the right answer. Is there any reason to use 302 redirects? Not really, as far as I can tell.

Note that 302 and 307 redirects aren't cached by default by browsers. If you previously issued a 301 redirect but want to un-do that. If people still have the cached 301 redirect in their browser they will continue to be taken to the target page regardless of whether the source page still has the redirect in place. Your options for fixing this ...
