into 2 groups. The static files
served by NginX and the HTML
Output from PHP served by
Apache HTTP Server.
It’s called reverse proxy

taking web user experience to the next level @draskolnikova @idkurniawan
The visitor will be
served by CDN-like
Server (Optimized
Result) after hit the
origin once. The
meaning once is, if
everyone hit the
origin server, the
other visitor will not
hit the origin again,
but will be served by
CDN-like Server.
