/*
 * Simple HTTP server.
 *
 * To test it:
 * 1) Run it on a port of your choice, e.g.:
 * $ php examples/http.php 8010
 * 2) In another terminal connect to some address on this port
 * and make GET or POST request(others are turned off here), e.g.:
 * $ nc -t 127.0.0.1 8010
 * POST /about HTTP/1.0
 * Content-Type: text/plain
 * Content-Length: 4
 * Connection: close
 * (press Enter)
 *
 * It will output
 * a=12
 * HTTP/1.0 200 OK
 * Content-Type: text/html; charset=ISO-8859-1
 * Connection: close
 *
 * $ nc -t 127.0.0.1 8010
 * GET /dump HTTP/1.0
 * Content-Type: text/plain
 * Content-Encoding: UTF-8
 * Connection: close
 * (press Enter)
 *
 * It will output:
 * HTTP/1.0 200 OK
 * Content-Type: text/html; charset=ISO-8859-1
 * Connection: close
 * (press Enter)
 *
 * $ nc -t 127.0.0.1 8010
 * GET /unknown HTTP/1.0
 * Connection: close
 *
 * It will output:
 * HTTP/1.0 200 OK
 * Content-Type: text/html; charset=ISO-8859-1
 * Connection: close
 *
 * 3) See what the server outputs on the previous terminal window.

The above example will output something similar to:

a=12
HTTP/1.0 200 OK
Content-Type: text/html; charset=ISO-8859-1
Connection: close

HTTP/1.0 200 OK
Content-Type: text/html; charset=ISO-8859-1
Connection: close
(press Enter)

HTTP/1.0 200 OK
Content-Type: text/html; charset=ISO-8859-1
Connection: close
