nmap http service probe failed for HTTP 1.1

[Enrico Milanese <enricomilanese () gmail com>]

Hello,

I experienced some issues during service identification on an HTTP server.
The remote service negotiates *only*  HTTP 1.1 connections.
The remote service discarded (connection close) all the HTTP 1.0 negotiations.

At this time the nmap-service-probes has only TCP probes with HTTP 1.0

"""
Probe TCP GetRequest q|GET / HTTP/1.0\r\n\r\n|
Probe TCP HTTPOptions q|OPTIONS / HTTP/1.0\r\n\r\n|
Probe TCP FourOhFourRequest q|GET /nice%20ports%2C/Tri%6Eity.txt%2ebak
HTTP/1.0\r\n\r\n|
"""

Is it possible to define another TCP probe for this scenario using
HTTP 1.1 negotiation?

Ex:
Probe TCP GetRequest q|GET / HTTP/1.1\r\nHost: www.example.com\r\n\r\n|

Do you see any drawbacks?

Regards
