defmodule Plug.Parsers.URLENCODED do
@moduledoc """
Parses urlencoded request body.
## Options
All options supported by `Plug.Conn.read_body/2` are also supported here.
They are repeated here for convenience:
* `:length` - sets the maximum number of bytes to read from the request,
defaults to 1_000_000 bytes
* `:read_length` - sets the amount of bytes to read at one time from the
underlying socket to fill the chunk, defaults to 1_000_000 bytes
* `:read_timeout` - sets the timeout for each socket read, defaults to
So by default, `Plug.Parsers` will read 1_000_000 bytes at a time from the
socket with an overall limit of 8_000_000 bytes.
