Not sure what mojo is or how useful this is to what you're working on, but SSE might be something to look into.
#!/usr/bin/perl --
print "Content-Type: text/event-stream\n\n";
while(true){
print "event: server-time\n";
$num++;
print "data: $num\n\n";
}
generates an SSE stream.
<!DOCTYPE HTML>
<html>
<head>
<title>Server-Side Event</title>
<script type="text/javascript">
function invokeSSE(){
var source = new EventSource('http://localhost/sse.pl');
source.addEventListener('server-time', function(e) {
document.getElementById('ticker').innerHTML = e.data + '<br>';
}, false);
source.addEventListener('open', function(e) {
//Connection Open
}, false);
source.addEventListener('error', function(e) {
if (e.readyState == EventSource.CLOSED) {
alert("Connection closed");
}
}, false);
}
</script>
</head>
<body onload="invokeSSE()">
<div id="ticker" name="ticker">
[TIME]
</div>
</body>
</html>
is a page to listen to SSE streams.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
