Based on the pcap you provided the content shows up in both packets. It looks like snort saw the retransmission and alerted on the duplicate.


Hope this helps.

Hi. Do you know why snort creates two alerts for one content match?
I am using the following rule for content match:

alert tcp any any -> any any (msg:"Hit!"; content:"Tree"; sid:1000001;)
The file which is requeste using HTTP and the logs created by snort in a pcap file are attached to this email.
Thanks
