Bypass Keyword
==============
.. role:: example-rule-emphasis
Suricata has a ``bypass`` keyword that can be used in signatures to exclude
traffic from further evaluation.
The ``bypass`` keyword is useful in cases where there is a large flow expected
(e.g. Netflix, Spotify, YouTube).
The ``bypass`` keyword is considered a post-match keyword.
