[OpenSIPS-Users] ratelimit per method per subscriber

[Jeff Pyle]

Hi Bogdan,

I understand the part about using memcache for keeping count, but I don't
understand how I can handle the temporal aspect of rate-limiting.  For
example, I can could invites, but I don't know how to count invites per
second, handle bursting, etc.  Any pointers?


Regards,
Jeff
