  • proto Example:
  • --proto-redir =http,https $URL ---

--proto-redir

Limit what protocols to allow on redirects. Protocols denied by --proto are not overridden by this option. See --proto for how protocols are represented.

Example, allow only HTTP and HTTPS on redirect:

curl --proto-redir -all,http,https http://example.com

By default curl only allows HTTP, HTTPS, FTP and FTPS on redirects (added in 7.65.2). Specifying all or +all enables all protocols on redirects, which is not good for security.
