* 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.

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    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
