Server

The server section configures and tunes the http server module Authelia uses.

Configuration

# Configuration options specific to the internal http server
server:
  # Buffers usually should be configured to be the same value.
  # Explanation at https://docs.authelia.com/configuration/server.html
  # Read buffer size configures the http server's maximum incoming request size in bytes.
  read_buffer_size: 4096
  # Write buffer size configures the http server's maximum outgoing response size in bytes.
  write_buffer_size: 4096

Buffer Sizes

The read and write buffer sizes generally should be the same. This is because when Authelia verifies if the user is authorized to visit a URL, it also sends back nearly the same size response (write_buffer_size) as the request (read_buffer_size).
