== Types
=== opts()
[source,erlang]

// @todo Document the shutdown option.
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 (#{})::
Middleware environment.
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)::
Maximum length of header values.
max_headers (100)::
Maximum number of headers allowed per request.
max_keepalive (100)::
Maximum number of requests allowed per connection.
max_request_line_length (8000)::
Maximum length of the request line.
max_method_length (32)::
Maximum length of the method.
middlewares ([cowboy_router, cowboy_handler])::
Middlewares to run for every request.
request_timeout (5000)::
Time in ms with no requests before Cowboy closes the connection.
== 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 `max_header_request_line_length` default was increased from 4096 to 8000.
