A clear guide to permanent and temporary redirects and why redirect chains should be avoided.

Use permanent redirects for permanent moves

A 301 or 308 is appropriate when a resource has permanently moved to a new URL.

Use temporary redirects for temporary changes

302 and 307 responses are useful when the original URL is expected to return later.

Avoid long chains

Redirecting A to B to C adds latency and complexity. Update internal links and redirect directly to the final destination where possible.
