PendingRequestFilter

object PendingRequestFilter

A module which allows clients to limit the number of pending requests per connection.

The effects of this filter are reflected in the stat "dispatcher/.../pending", which is a sum over per-host connections of dispatched requests between client and server. If the limit is configured as L and there are N per-host connections, "dispatcher/.../pending" will be no greater than L * N.

Note that the "pending" stat recorded in c.t.f.StatsFilter can be greater than L * N because requests can be between c.t.f.StatsFilter and c.t.f.PendingRequestFilter when the stat is read.
