Buffer
======

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.

* :ref:`v2 API reference <envoy_api_msg_config.filter.http.buffer.v2.Buffer>`
* This filter should be configured with the name *envoy.buffer*.

Per-Route Configuration
-----------------------

The buffer filter configuration can be overridden or disabled on a per-route basis by providing a
:ref:`BufferPerRoute <envoy_api_msg_config.filter.http.buffer.v2.BufferPerRoute>` configuration on
the virtual host, route, or weighted cluster.
