Description

Using rule
alert ip any any -> any any (content:"HTTP/2.loc"; sid:11;)

on attached pcap

with stream.reassembly.toserver-chunk-size=25

does not trigger an alert

It does trigger the alert without the setting.

I fear we might have an evasion if I split the packets over the default value of 2560...
