I am trying to apply SSL to a staging server.
At the moment, we already have an ssl installed by an "unknown" guy in the production server.
While going through prd server's apache settings, I found this in
<VirtualHost *:80> section
RewriteRule ^/(.*) https://%{HTTP_HOST}/%1 [NC,R,L]
It seems like redirection rule to HTTPS but I want to understand what this means fully. What does this mean exactly?
