Hi,
I have a FP with this simply signature and joigned pcap file:
  alert tcp any any -> any 80 (msg:"suricata pcre I test"; flow:to_server,established; content:".php/"; nocase; http_raw_uri; 
pcre:"/^[^\n]*\.php\/$/Ii"; classtype:attempted-admin; sid:9410351; rev:1; )

If I remove "$" on pcre, suricata fire and it's true.
If I remember correctly, "$" are http_raw_uri ending.
I have tested with suricata rule like "alert http any..." but FP again.
Anyone confirm please? if yes Im open a new ticket on redmine.
Of couse, snort not fire.
Regards
Rmkml

PS: simulated http with wget "http://ibiblio.org/abc.php/a"
