Frequently Asked Questions
1. What is the difference between 401 and 403?
401 means unauthenticated (not logged in or invalid credentials, authenticate first); 403 means authenticated but not allowed to access the resource, so re-login does not help.
2. Should I use 301 or 302?
Use 301 when a resource moves permanently (passes SEO weight); use 302 for a temporary redirect, which browsers and search engines do not cache.
