<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>
</div>
<script>

var ls = document.getElementById('ledState').innerHTML;

window.location.href = 'gpio?off=2';
else

<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.
