::: cowboy_protocol

The `cowboy_protocol` module implements HTTP/1.1 and HTTP/1.0 
as a Ranch protocol.

:: Types

: opts() = [{compress, boolean()}
	| {env, cowboy_middleware:env()}
	| {max_empty_lines, non_neg_integer()}
	| {max_header_name_length, non_neg_integer()}
	| {max_header_value_length, non_neg_integer()}
	| {max_headers, non_neg_integer()}
	| {max_keepalive, non_neg_integer()}
	| {max_request_line_length, non_neg_integer()}
	| {middlewares, [module()]}
	| {onresponse, cowboy:onresponse_fun()}
	| {timeout, timeout()}]

Configuration for the HTTP protocol handler.

This configuration is passed to Cowboy when starting listeners
using `cowboy:start_http/4` or `cowboy:start_https/4` functions.

It can be updated without restarting listeners using the
Ranch functions `ranch:get_protocol_options/1` and
`ranch:set_protocol_options/2`.
