-@section sslinfo SSL info callbacks
-
-OpenSSL allows you to receive callbacks for various events defined in a
-bitmask in openssl/ssl.h.  The events include stuff like TLS Alerts.
-
-By default, lws doesn't register for these callbacks.
-
-However if you set the info.ssl_info_event_mask to nonzero (ie, set some
-of the bits in it like `SSL_CB_ALERT` at vhost creation time, then
-connections to that vhost will call back using LWS_CALLBACK_SSL_INFO
-for the wsi, and the `in` parameter will be pointing to a struct of
-related args:
-
-```
-struct lws_ssl_info {
-	int where;
-	int ret;
-};
-```
-
-The default callback handler in lws has a handler for LWS_CALLBACK_SSL_INFO
-which prints the related information,  You can test it using the switch
--S -s  on `libwebsockets-test-server-v2.0`.
-
-Returning nonzero from the callback will close the wsi.

-Lws provides a "factory" application

-
-and a test application which implements the generic lws server test apps
-
-https://github.com/warmcat/lws-esp32-test-server-demos
-
-The behaviours of the generic factory are are quite rich, and cover uploading SSL certs through factory and user configuration, AP selection and passphrase entry, and managing a switch to allow the user to force entry to user setup mode at boot subsequently.
-
-The factory app comes with partitioning for a 1MB factory partition containing that app and data, and a single 2.9MB OTA partition containing the main app.
-
-The factory app is able to do OTA updates for both the factory and OTA partition slots; updating the factory slot first writes the new image to the OTA slot and copies it into place at the next boot, after which the user can reload the OTA slot.

-# lws-meta protocol
-
-lws-meta is a lightweight ws subprotocol that accepts other ws connections
-to the same server inside it and multiplexes their access to the connection.
-
-```
-  Client                                                    Server
- 
-  conn1: \                                                / :conn1
-  conn2:  =   mux ------ lws-meta ws protocol ----- mux  =  :conn2
-  conn3: /                                                \ :conn3
-```
-
-You may have n client ws connections back to the server, but you now
-only have one tcp connection (and one SSL wrapper if using SSL) instead
-of n of those.
-
-If you currently make multiple ws connections back to the server, so you
-can have different protocols active in one webpage, this if for you.
-
- - The subprotocol code for the connections inside a lws-meta connection
-   need zero changes from being a normal ws connection.  It is unaware
-   it is inside an lws-meta parent connection.
-
- - The traffic on the lws-meta connection is indistinguishable from
-   standard ws traffic, so intermediaries won't object to it
-
- - The multiplexing is done in the protocol, **not by an extension**.  So
-   it's compatible with all browsers.
-
- - Javascript helper code is provided to very simply use lws-meta
-   protocol instead of direct connections.  The lws test server has
-   been converted to use this by default.
-
-# Converting your server
-
-1) include the provided lws-meta plugin (plugins/protocl_lws_meta.c) as an
-active protocol for your server.  You can do that using runtime plugins, or
-include the plugin sources into your server at build-time.  The lws test
-server uses the latter approach.
-
-That's all you need to do on the server side.
-
-# Converting your browser JS
-
-1) import lws-common.js
-
-2) Instantiate a parent lws-meta connection object
-
-```
-var lws_meta = new lws_meta_ws();
-```
-
-3) Connect the lws-meta object to your server
-
-```
-lws_meta.new_parent(get_appropriate_ws_url("?mirror=" + mirror_name));
-```
-
-4) Convert your actual ws connections to go via the lws_meta object
-
-```
-var my_ws = lws_meta.new_ws("", "dumb-increment-protocol");
-```
-
-The first arg is the URL path, the second arg is the ws protocol you want.
-
-That's it.  my_ws will get `onopen()`, `onmessage()` etc calls as before.
-
-# lws-meta wire protocol
-
-lws-meta works by adding some bytes at the start of a message indicating
-which channel the message applies to.
-
-Channel messages are atomic on the wire.  The reason is if we tried to
-intersperse other channel fragments between one channels message fragments,
-an intermediary would observe violations of the ws framing rule about
-having to start a message with TEXT or BINARY, and use only CONTINUATION
-for the subsequent fragments.  Eg
-
-```
-  [ ch1 TEXT NOFIN ] [ ch2 BINARY FIN ] [ ch1 CONTINUATION FIN ]
-```
-
-is illegal to an observer that doesn't understand lws-meta headers in the
-packet payloads.  So to avoid this situation, only complete messages may
-be sent from one subchannel in each direction at a time.
-
-Consequently, only the first fragment of each message is modified to
-have the extra two bytes identifying the subchannel it is aimed at, since
-the rest of the message from the same subchannel is defined to follow.
-
-If it makes latencies, modify the protocol sending large messages to
-send smaller messages, so the transmission of messages from other channels
-can be sent inbetween the smaller messages.
-
-## lws-meta commands
-
-1) CSTRING indicates a string terminated by 0x00 byte
-
-2) Channel IDs are sent with 0x20 added to them, to guarantee valid UTF-8
-
-### 0x41: RX: LWS_META_CMD_OPEN_SUBCHANNEL
-
-   - CSTRING: protocol name
-   - CSTRING: url
-   - CSTRING: cookie (7 bytes max)
-
-Client is requesting to open a new channel with the given protocol name,
-at the given url.  The cookie (eg, channel name) is only used in
-LWS_META_CMD_OPEN_RESULT, when the channel id is assigned, so it is
-applied to the right channel.
-
-### 0x42: TX: LWS_META_CMD_OPEN_RESULT
-
-   - CSTRING cookie
-   - BYTE channel id (0 indicates failed)
-   - CSTRING: selected protocol name
-
-The server is informing the client of the results of a previous
-open request.  The cookie the client sent to identify the request
-is returned along with a channel id to be used subsequently.  If
-the channel ID is 0 (after subtracting the transport offset of
-0x20) then the open request has failed.
-
-### 0x43: TX: LWS_META_CMD_CLOSE_NOTIFY
-
-   - BYTE channel id
-   - BYTE: payload length + 0x20
-   - BYTE: close code MSB
-   - BYTE: close code LSB
-   - PAYLOAD: payload (< 123 bytes)
-
-Server notifies the client that a child has closed, for whatever reason.
-
-### 0x44: RX: LWS_META_CMD_CLOSE_RQ
-   - BYTE: channel id
-   - BYTE: payload length + 0x20
-   - BYTE: close code MSB
-   - BYTE: close code LSB
-   - PAYLOAD: payload (< 123 bytes)
-
-The client requests to close a child connection
-
-### 0x45: TX: LWS_META_CMD_WRITE
-
-   - BYTE: channel id
-
-Normal write of payload n from lws-meta perspective is actually
-LWS_META_CMD_WRITE, channel id, then (n - 2) bytes of payload
-
-The command only appears at the start of a message, continuations do
-not have the command.
-
-## Protocol Notes
-
- - Once the subchannel is up, overhead is only +2 bytes per message
-
- - Close reasons are supported in both directions
-
- - Ping and Pong are only supported at the lws-meta level, using normal ws ping and pong packets.
-
- - Only the final close of the tcp lws-meta connection itself goes out as
-   a normal ws close frame.  Subchannels close is done in a normal TEXT
-   message using LWS_META_CMD_CLOSE_RQ and then the close packet payload.
-   This is so intermediaries do not mistake subchannel closures for the
-   tcp / ws link going down.
-
-   Messages that start with LWS_META_CMD_OPEN_SUBCHANNEL only contain those
-   commands but may contain any number of them for the whole duration of the
-   message.  The lws-meta js support collects child open requests made before
-   the parent lws-meta connection is open, and dumps them all in a single
-   message when it does open.
-
-   Messages that start with LWS_META_CMD_OPEN_RESULT or LWS_META_CMD_CLOSE_NOTIFY
-   only contain those two commands, but they may contain any number of them
-   for the whole duration of the message.
-
-
-# Current Implemention Limitations
-
- - only server side is supported in lws.  The client side JS for
-   a browser is supported.
-
- - max number of child connections per parent at the moment is 8
-
- - child connection URL paramter when opening the connection is
-   ignored
-
- - there is no ah attached when the child connections are
-   established inside the lws-meta parent.  So header access
-   functions will fail.

 Changelog
 ---------
 
-v2.3.0
-======
-
- - ESP32 OpenSSL support for client and server
-
- - ESP32 4 x WLAN credential slots may be configured
-
- - Libevent event loop support
-
- - SOCKS5 proxy support
-
- - lws_meta protocol for websocket connection multiplexing
-
- - lws_vhost_destroy() added... allows dynamic removal of listening
-   vhosts.  Vhosts with shared listen sockets adopt the listen socket
-   automatically if the owner is destroyed.
-
- - IPv6 on Windows
-
- - Improved CGI handling suitable for general CGI scripting, eg, PHP
-
- - Convert even the "old style" test servers to use statically included
-   plugin sources
-
- - LWS_WITH_STATS cmake option dumps resource usage and timing information
-   every few seconds to debug log, including latency information about
-   delay from asking for writeable callback to getting it
-
- - Large (> 2GB) files may be served
-
- - LWS_WITH_HTTP_PROXY Cmake option adds proxying mounts
-
- - Workaround for libev build by disabling -Werror on the test app
-
- - HTTP2 support disabled since no way to serve websockets on it
-
-
 v2.2.0
