Nginx reverse cache 301 redirects (permanent)

Kendall Hopkins asked:

Is it possible to have Nginx cache all 301 redirect requests for proxy_pass?

For example:

Request #1: Client A requests /some/path -> sent to proxy_pass -> results in 301 redirect to /some/other/path -> nginx caches this response since it’s a 301 redirect.

Request #2: Client B requests /some/path -> nginx returns cached 301 redirect to /some/other/path.

My answer:


nginx already can cache 301 redirects. You can change the amount of time they are cached with the proxy_cache_valid directive:

proxy_cache_valid 301 365d; # Cache permanent redirects for a whole year
