+Configuration for the HTTP/1.1 protocol.
+
+This configuration is passed to Cowboy when starting listeners
+using `cowboy:start_clear/4` or `cowboy:start_tls/4` functions.
+
+It can be updated without restarting listeners using the
+Ranch functions `ranch:get_protocol_options/1` and
+`ranch:set_protocol_options/2`.
+
+=== Option descriptions
+
+The default value is given next to the option name.
+
+env (#{})::

+
+max_empty_lines (5)::
+    Maximum number of empty lines before a request.
+
+max_header_name_length (64)::
+    Maximum length of header names.
+
+max_header_value_length (4096)::

+
+max_keepalive (100)::

+
+== Changelog
+
+* *2.0*: The `max_method_length` option was added.
+* *2.0*: The `env` option is now a map instead of a proplist.

+* *2.0*: The `compress` option was temporarily removed.
+* *2.0*: Options are now a map instead of a proplist.
