* Servidor HTTP simple.
*
* Para probarlo:
* 1) Ejecútelo en el puerto de su elección, i.e. :
* $ php examples/http.php 8010
* 2) En otro terminal, conéctese a una dirección de este puerto
* y realice una solicitud GET o POST (las otras están deshabilitadas aquí),
* i.e. :
* $ nc -t 127.0.0.1 8010
* POST /about HTTP/1.0
* Content-Type: text/plain
* Content-Length: 4
* Connection: close
* (presione Enter)
*
* Debería mostrar:
* 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
* (presione Enter)
*
* Debería mostrar:
* HTTP/1.0 200 OK
* Content-Type: text/html; charset=ISO-8859-1
* Connection: close
* (presione Enter)
*
* $ nc -t 127.0.0.1 8010
* GET /unknown HTTP/1.0
* Connection: close
*
* Debería mostrar:
* HTTP/1.0 200 OK
* Content-Type: text/html; charset=ISO-8859-1
* Connection: close
*
* 3) Observe lo que muestra el servidor en el terminal anterior.

El resultado del ejemplo
sería algo similar a:
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
(presione Enter)
HTTP/1.0 200 OK
Content-Type: text/html; charset=ISO-8859-1
Connection: close
