Greg Senia commented on AMBARI-18770:
-------------------------------------
Curl Manpage:
-L, --location
(HTTP/HTTPS) If the server reports that the requested page has
moved to a different location (indicated with a Location: header and a 3XX
response code), this
option will make curl redo the request on the new place. If used
together with -i, --include or -I, --head, headers from all requested pages
will be shown.
When authentication is used, curl only sends its credentials to
the initial host. If a redirect takes curl to a different host, it won't be
able to intercept
the user+password. See also --location-trusted on how to change
this. You can limit the amount of redirects to follow by using the --max-redirs
option.
When curl follows a redirect and the request is not a plain GET
(for example POST or PUT), it will do the following request with a GET if the
HTTP response was
301, 302, or 303. If the response code was any other 3xx code,
curl will re-send the following request using the same unmodified method.
You can tell curl to not change the non-GET request method
to GET after a 30x response by using the dedicated options for that: --post301,
--post302 and
-post303.
--location-trusted
(HTTP/HTTPS) Like -L, --location, but will allow sending the name
+ password to all hosts that the site may redirect to. This may or may not
introduce a secu-
rity breach if the site redirects you to a site to which you'll
send your authentication info (which is plaintext in the case of HTTP Basic
authentication).
