Here's the rule that one would expect to trigger. alert tcp $EXTERNAL_NET any -> $HTTP_SERVERS $HTTP_PORTS (msg:"WEB-CGI test.cgi access"; flow:to_server,established; uricontent:"/test.cgi"; nocase; classtype:web-application-activity; sid:1646; rev:5;) I'm left to think that I must be making a mistake somehow with my playback testing, but I'm not sure what. Any ideas?
your rule has flow:to_server,established in it... could it be that your container snort hasn't seen the previous 3-way handshake packets and so doesn't consider this packet as "established"? we've seen similar when snort has flushed "old" unprocessed packets to make room for new ones in a heavy flow, low memory, high cpu usage situation... -- NOTE: No off-list assistance is given without prior approval.
