Subject: Add support for a new keyword to inspect http_host header.
X-Git-Tag: suricata-1.4.1~44
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c4ce19a1be4cbd08d2ea6559cffc52106c900f26;p=thirdparty%2Fsuricata.git

Add support for a new keyword to inspect http_host header.

The corresponding content keyword would now be - http_host.
The corresponding pcre modifier would be W.
