Check if apache URL redirects work with curl

With curl you can check if redirects in your apache or .htaccess configuration works. You can add the options -I and -L for a better result, if there are multiple redirects. The option -I will get only the header of the page and option -L allows multiple redirects. In this example, the page http://www.example.com/ gets redirected to https://example.com/, with SSL and no www:

$ curl -IL http://www.example.com/
HTTP/1.1 301 Moved Permanently
Date: Sat, 08 Sep 2018 20:08:07 GMT
Server: Apache/2.4.25 (Debian)
Location: https://www.example.com/
Connection: close
Content-Type: text/html; charset=iso-8859-1

HTTP/1.1 301 Moved Permanently

from $ man curl:

-I, --head
(HTTP/FTP/FILE)  Fetch the HTTP-header only! HTTP-servers feature the command HEAD which this uses to get nothing but the header of a document. When used on an FTP or FILE file, curl displays the file size and last modification time only.

-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.
