mod_limits: Allow configuration of general 's2s' limit, and have s2sout inherit from s2sin Most people don't currently have a limit set for s2sout, as usually such sessions don't have significant incoming traffic. However, having limits in place is still sensible, especially with the rising use of bidi. The goal here is to switch people to a general 's2s' limit, which s2sin and s2sout both inherit from. Due to the widespread existence of 's2sin' in existing configurations, s2sout will inherit from that unless explicitly set.
