Description Marian Rehak 2022-04-21 14:54:51 UTC
curl follows HTTP(S) redirects when asked to. curl also supports authentication. When a user and password are provided for a URL with a given hostname, curl makes an effort to not pass on those credentials to other hosts in redirects unless given permission with a special option.
