Example for prezentation: Inverting Client-Server Architecture

Installing

Copy server-client.html into your server. E.g. it is http://aurelijus.banelis.lt/server-client.html Run php -S localhost:12345 localhost-server.php You should see 3 in http://localhost:12345/?a=1&b=2 You should see 1+2 = 3 when opened server-client.html on your own server.
