Dear Andy and list,

    Thank you for libwebsockets. We are using libwebsockets on a client. We want to handle the server sending a close code of 1013 "Try Again Later", as mentioned on https://developer.mozilla.org/en-US/docs/Web/API/CloseEvent, from the server to the client. The current code in client-parser.c in the case statement LWSWSOPC_CLOSE looks like it changes close codes to 1002 LWS_CLOSE_STATUS_PROTOCOL_ERR. This change went in 7c2868. Is there any reason why we should not pass the close code through instead of overriding it to 1002?

    Thank you for any input and help,
    Michael Zendels
