Protocols denied by --proto are 19not overridden by this option. See --proto for how protocols are represented. 20 21Example, allow only HTTP and HTTPS on redirect: 22 23 curl --proto-redir -all,http,https http://example.com 24 25By default curl only allows HTTP, HTTPS, FTP and FTPS on redirects 26(added in 7.65.2). Specifying *all* or *+all* enables all protocols on 27redirects, which is not good for security. 28
