How to handle a 305 response
Follow the Location header. Most HTTP clients do this automatically, and curl -L follows redirects on the command line. Update links and sitemaps that point at permanently redirected URLs.
Check the status code a URL returns from the command line:
curl -s -o /dev/null -w "%{http_code}\n" https://example.comHow to return 305 from your server
