Sending browser cookies during a 302 redirect

According to this blog post: http://blog.dubbelboer.com/2012/11/25/302-cookie.html all major browsers, IE (6, 7, 8, 9, 10), FF (17), Safari (6.0.2), Opera (12.11) both on Windows and Mac, set cookies on redirects. This is true for both 301 and 302 redirects.

As @Benni noted :

https://www.chromium.org/administrators/policy-list-3/cookie-legacy-samesite-policies

The SameSite attribute of a cookie specifies whether the cookie should be restricted to a first-party or same-site context. Several values of SameSite are allowed:

• A cookie with "SameSite=Strict" will only be sent with a same-site request.
• A cookie with "SameSite=Lax" will be sent with a same-site request, or a cross-site top-level navigation with a "safe" HTTP method.
• A cookie with "SameSite=None" will be sent with both same-site and cross-site requests.

One notice (to save developer's life):

IE and Edge are ignoring Set-Cookie in redirect response when domain of the cookie is localhost.

Solution:

Use 127.0.0.1 instead of localhost.

Most browser are accepting cookies on 302 redirects. I was quite sure of that, but I made a little search. Not all modern browsers. Internet archive Link from a now removed/dead/ microsoft connect Q/A on Silverlight Client HTTP Stack ignores Set-Cookie on 302 Redirect Responses (2010)

I think we now have a replacement for IE6 and it's Windows Mobile browsers...
