[mod-security-users] warning Patern match "^$" at HEADER

[Markus R. <we...@mr...>]

i get a lot of:

mod_security: Warning. Pattern match "^$" at HEADER [hostname "www.myserver.xx"] [uri "/cgi-bin/somescript.pl?someparams"]

in my error log.

my conf shows:

        # only valid protocols
        SecFilterSelective SERVER_PROTOCOL !^HTTP/(0\.9|1\.0|1\.1)$
        SecFilterSelective REQUEST_METHOD !^(GET|HEAD|POST)$
        # host header present
        # SecFilterSelective HTTP_Host ^$


so as the line is commented this error shouldn't occur.

it means that http/1.1 is "spoken" but no host-header is sent...

is this something i have to take care? does it mean, that people couldn't open our pages?
