Module Websocket.Connection_close_reason

type t =
| Normal_closure

1000 indicates a normal closure, meaning that the purpose for which the connection was established has been fulfilled.

| Endpoint_going_away

1001 indicates that an endpoint is "going away", such as a server going down or a browser having navigated away from a page.

| Protocol_error

1002 indicates that an endpoint is terminating the connection due to a protocol error.

| Cannot_accept_data

1003 indicates that an endpoint is terminating the connection because it has received a type of data it cannot accept (e.g., an endpoint that understands only text data MAY send this if it receives a binary message).

| Reserved_0

Reserved. The specific meaning might be defined in the future.

| No_status_code

1005 is a reserved value and MUST NOT be set as a status code in a Close control frame by an endpoint. It is designated for use in applications expecting a status code to indicate that no status code was actually present.

| Closed_abnormally

1006 is a reserved value and MUST NOT be set as a status code in a Close control frame by an endpoint. It is designated for use in applications expecting a status code to indicate that the connection was closed abnormally, e.g., without sending or receiving a Close control frame.

| Invalid_message_sent

1007 indicates that an endpoint is terminating the connection because it has received data within a message that was not consistent with the type of the message (e.g., non-UTF-8 RFC3629 data within a text message).

| Policy_violation

1008 indicates that an endpoint is terminating the connection because it has received a message that violates its policy. This is a generic status code that can be returned when there is no other more suitable status code (e.g., 1003 or 1009) or if there is a need to hide specific details about the policy.

| Message_too_large

1009 indicates that an endpoint is terminating the connection because it has received a message that is too big for it to process.

| Invalid_handshake

1010 indicates that an endpoint (client) is terminating the connection because it has expected the server to negotiate one or more extension, but the server didn't return them in the response message of the WebSocket handshake. The list of extensions that are needed SHOULD appear in the /reason/ part of the Close frame. Note that this status code is not used by the server, because it can fail the WebSocket handshake instead.

| Unexpected_condition

1011 indicates that a server is terminating the connection because it encountered an unexpected condition that prevented it from fulfilling the request.

| Tls_handshake_failure

1015 is a reserved value and MUST NOT be set as a status code in a Close control frame by an endpoint. It is designated for use in applications expecting a status code to indicate that the connection was closed due to a failure to perform a TLS handshake (e.g., the server certificate can't be verified).
