   The following settings can be configured for HTTP. These settings also use the common <<modules-network,network settings>>.
   
  -NOTE: HTTP settings cannot be updated dynamically. You must configure these settings in the {es} <<settings, configuration file>>
  -and restart {es} for changes to take effect.
  -
   `http.port`::
  +(<<static-cluster-setting,Static>>)
   A bind port range. Defaults to `9200-9300`.
   
   `http.publish_port`::
  +(<<static-cluster-setting,Static>>)
   The port that HTTP clients should use when
   communicating with this node. Useful when a cluster node is behind a
   proxy or firewall and the `http.port` is not directly addressable
   from the outside. Defaults to the actual port assigned via `http.port`.
   
   `http.bind_host`::
  +(<<static-cluster-setting,Static>>)
   The host address to bind the HTTP service to. Defaults to `http.host` (if set) or `network.bind_host`.
   
   `http.publish_host`::
  +(<<static-cluster-setting,Static>>)
   The host address to publish for HTTP clients to connect to. Defaults to `http.host` (if set) or `network.publish_host`.
   
   `http.host`::
  +(<<static-cluster-setting,Static>>)
   Used to set the `http.bind_host` and the `http.publish_host`.
   
   `http.max_content_length`::
  +(<<static-cluster-setting,Static>>)
   The max content of an HTTP request. Defaults to `100MB`.
   
   `http.max_initial_line_length`::
  +(<<static-cluster-setting,Static>>)
   The max length of an HTTP URL. Defaults to `4KB`.
   
   `http.max_header_size`::
  +(<<static-cluster-setting,Static>>)
   The max size of allowed headers. Defaults to `8KB`.
   
   [[http-compression]]
   // tag::http-compression-tag[]
   `http.compression` {ess-icon}::
  +(<<static-cluster-setting,Static>>)
   Support for compression when possible (with Accept-Encoding). If HTTPS is enabled, defaults to `false`. Otherwise, defaults to `true`.
   +
   Disabling compression for HTTPS mitigates potential security risks, such as a
  
positive.code: // end::http-cors-allow-credentials-tag[]
  
  `http.detailed_errors.enabled`::
  If `true`, enables the output of detailed error messages and stack traces in the response output. Defaults to `true`.
  +
  If `false`, use the `error_trace` parameter to <<common-options-error-options,enable stack traces>> and return detailed error messages. Otherwise, only a simple message will be returned.
  
  `http.pipelining.max_events`::
  The maximum number of events to be queued up in memory before an HTTP connection is closed, defaults to `10000`.
  
  `http.max_warning_header_count`::
  The maximum number of warning headers in client HTTP responses. Defaults to `unbounded`.
  
  `http.max_warning_header_size`::
  The maximum total size of warning headers in client HTTP responses. Defaults to `unbounded`.
  
  `http.tcp.no_delay`::
  Enable or disable the {wikipedia}/Nagle%27s_algorithm[TCP no delay]
  setting. Defaults to `network.tcp.no_delay`.
  
  `http.tcp.keep_alive`::
  Configures the `SO_KEEPALIVE` option for this socket, which
  determines whether it sends TCP keepalive probes.
  Defaults to `network.tcp.keep_alive`.
  
  `http.tcp.keep_idle`:: Configures the `TCP_KEEPIDLE` option for this socket, which
  determines the time in seconds that a connection must be idle before
  starting to send TCP keepalive probes. Defaults to `network.tcp.keep_idle`, which
  uses the system default. This value cannot exceed `300` seconds. Only applicable on
  Linux and macOS, and requires Java 11 or newer.
  
  `http.tcp.keep_interval`:: Configures the `TCP_KEEPINTVL` option for this socket,
  which determines the time in seconds between sending TCP keepalive probes.
  Defaults to `network.tcp.keep_interval`, which uses the system default.
  This value cannot exceed `300` seconds. Only applicable on Linux and macOS, and requires
  Java 11 or newer.
  
  `http.tcp.keep_count`:: Configures the `TCP_KEEPCNT` option for this socket, which
  determines the number of unacknowledged TCP keepalive probes that may be
  sent on a connection before it is dropped. Defaults to `network.tcp.keep_count`,
  which uses the system default. Only applicable on Linux and macOS, and
  requires Java 11 or newer.
  
  `http.tcp.reuse_address`::
  Should an address be reused or not. Defaults to `network.tcp.reuse_address`.
  
  `http.tcp.send_buffer_size`::
  The size of the TCP send buffer (specified with <<size-units,size units>>).
  Defaults to `network.tcp.send_buffer_size`.
  
  `http.tcp.receive_buffer_size`::
  The size of the TCP receive buffer (specified with <<size-units,size units>>).
  Defaults to `network.tcp.receive_buffer_size`.
  
  
negative.code: [[http-cors-allow-origin]]
  // tag::http-cors-allow-origin-tag[]
  `http.cors.allow-origin` {ess-icon}::
  (<<static-cluster-setting,Static>>)
  Which origins to allow. If you prepend and append a forward slash (`/`) to the value, this will be treated as a regular expression, allowing you to support HTTP and HTTPs. For example, using `/https?:\/\/localhost(:[0-9]+)?/` would return the request header appropriately in both cases. Defaults to no origins allowed.
  +
  IMPORTANT: A wildcard (`*`) is a valid value but is considered a security risk, as your {es} instance is open to cross origin requests from *anywhere*.
