Wie Sie Firefox dazu bringen, HTTP / 1.1 zu verwenden

Es gibt diesen Webserver in Python (Code siehe Ende des Beitrags). Bei jeder Verbindung von Firefox meldet der Webserver HTTP / 1.0.

*.*.*.* - - [17/Feb/2016 15:50:59] "GET /?size=100 HTTP/1.0" 200 - 

Mit wgetwird HTTP / 1.1 verwendet:

*.*.*.* - - [17/Feb/2016 15:16:37] "GET /?size=488 HTTP/1.1" 200 - 

Mit netcat:

$ nc *.*.*.* 8000 GET ?size=10 HTTP/1.1  HTTP/1.1 200 OK Server: BaseHTTP/0.3 Python/2.7.10 Date: Wed, 17 Feb 2016 14:58:48 GMT Content-Length: 10  [content] 

und

$ nc *.*.*.* 8000 GET ?size=20 HTTP/1.0  HTTP/1.1 200 OK Server: BaseHTTP/0.3 Python/2.7.10 Date: Wed, 17 Feb 2016 14:58:59 GMT Content-Length: 20  [content] 

Wie kann Firefox angewiesen werden, HTTP / 1.1 zu verwenden?
