Description

Processing all of the attached pcaps and rules (all contain one or two rules and a generally on or two tcp sessions). These all appear to be valid http sessions but we don't seem to properly identify them as http traffic or fire on the attached rules. Snort however does.

src/suricata -c suricata.yaml -s 2008396.rule -r 2008396.pcap -l ./ not seen as valid http
src/suricata -c suricata.yaml -s 2008469.rule -r 2008469.pcap -l ./ not seen as valid http
src/suricata -c suricata.yaml -s 2009237.rule -r 2009237.pcap -l ./ not seen as valid http

all result in ...
