Sometimes in a session the same meta keys and values are generated.
For example if you had a session that contained multiple jpg files, the forensic fingerprint meta would fire for each jpg file in the session.
There doesn't seem to be much to gain from this,as your would have multiple
filetype = 'jpg'
saved for the session.
If this is repeated many times over many sessions then eventually this has an issue with packet retention as you are saving duplicate meta per packet over lots of packets.
Is there a way that if a session has already been tagged with MetaKey MyMeta=MyValue then further occurrences of MyMeta=MyValue are not registered?
