What is a redirect chain?
A redirect chain is the path a browser follows from the original URL to the final URL, usually through 301, 302, 303, 307, or 308 responses.
Why should I check redirects?
Broken, long, or unexpected redirect chains can slow down websites, confuse users, and create SEO problems.
What is the difference between 301 and 302?
A 301 redirect is generally permanent. A 302 redirect is generally temporary. Search engines may treat them differently.
Why are private URLs blocked?
Local, private, and reserved addresses are blocked to prevent unsafe server-side requests.
