Jimmy Jones commented on BIT-1257:
----------------------------------
Agreed there isn't a good way to identify it being the same file. However with
the attached sample the two downloads do get merged into one, which I think is
incorrect behavior.
> Same file id generated for potentially different files
> ------------------------------------------------------

> Key: BIT-1257
> URL: https://bro-tracker.atlassian.net/browse/BIT-1257
> Project: Bro Issue Tracker
> Issue Type: Problem
> Components: Bro
> Affects Versions: git/master, 2.3
> Environment: CentOS 6
> Reporter: Jimmy Jones
> Attachments: fa.bro, sample-samefileid.pcap
>
>
> Attached sample contains two HTTP downloads of the same URL from the same
> client, but there are no guarantees that the files is actually the same (no
> Etags etc - in this case it actually is the same, but lets pretend they were
> different...). However the file analysis framework seems to give the same
> file ID in file_name and file_chunk for both downloads.
> Think this is something to do with Range requests as doesn't happen if do
> "normal" HTTP requests.
