<h1>How it works</h1>
<p> Each time the server detects a tag of the form <code>&lt;!--#name--&gt;</code> in a .shtml, .ssi or .shtm file
where <code>name</code> appears as one of the tags supplied to <code>http_set_ssi_handler</code> in the <code>pcConfigSSITags</code> array,
an insert string is appended after the tag string in file and sent back to the client.</p>
<p>A CGI handler function is called each time the server is asked for a file
whose name was previously registered as a CGI function using a call to <code>http_set_cgi_handler</code>.
This function allows you to access the parameters provided along with the URI.</p>

<h1>How it works</h1>
<p>This demo uses 2 WebScokets. Status parameters are streamed by the server in JSON format every 2 seconds.
A <code>websocket_task</code> is created each time a specific URI is requested.</p>
<p>ADC values are being continuously polled by the client (i.e. your browser).
Each time a WebSocket frame is received on the server side, <code>websocket_cb</code> function is being called.</p>

/* tls_server_bearssl - simple BearSSL TLS server that outputs some statistics to a connecting client,
* then closes the socket.
*
* Uses code from the server_basic example in BearSSL and the tls_server example.
*
* To test this program, connect to the ESP using openssl command line like this:
*
* openssl s_client -connect 192.168.66.209:800
*
* The openssl command line client will print some information for the (self-signed) server certificate,
* then after a couple of seconds (validation) there will be a few lines of text output sent from the ESP.
*
* See the certificate.h and key.h files for private key & certificate, plus information for generation.

* Note that the behavior of this SSI mechanism is somewhat different from the

* replacing the tag entirely. This allows for an implementation that does not
* require significant additional buffering of output data yet which will still
* offer usable SSI functionality. One downside to this approach is when
* attempting to use SSI within JavaScript. The SSI tag is structured to
* resemble an HTML comment but this syntax does not constitute a comment
* within JavaScript and, hence, leaving the tag in place will result in
* problems in these cases. To work around this, any SSI tag which needs to
* output JavaScript code must do so in an encapsulated way, sending the whole
* HTML <script>...</script> section as a single include.

This is a basic HTTP server with WebSockets based on httpd from LwIP.
WebSockets implementation supports binary and text modes. Multiple sockets are supported. Continuation frames are not implemented.
By default, a WebSocket is closed after 20 seconds of inactivity to conserve memory. This behavior can be changed by overriding `WS_TIMEOUT` option.
To enable debugging extra flags `-DLWIP_DEBUG=1 -DHTTPD_DEBUG=LWIP_DBG_ON` should be passed at compile-time.
This module expects your project to provide "fsdata.c" created with "makefsdata" utility.
See examples/http_server.
