The buffer filter is used to stop filter iteration and wait for a fully buffered complete request. This is useful in different situations including protecting some applications from having to deal with partial requests and high network latency.

Per-Route Configuration

The buffer filter configuration can be overridden or disabled on a per-route basis by providing a BufferPerRoute configuration on the virtual host, route, or weighted cluster.

Statistics

The buffer filter outputs statistics in the http..buffer. namespace. The stat prefix comes from the owning HTTP connection manager.
