in ajax, node can only take up to 6 requests if no response is set during
that time.
see the code:
on the server:
var http = require('http');
http.createServer(onResponse).listen(9999);
function onResponse(req, res){
console.log('req received');
setTimeout(function(){
res.writeHead(200);
res.end("console.log('response sent')");
},6000);
}
on the client (using jquery and jsonp):
<script type="text/javascript" src="jquery.min.js"></script>
<script type="text/javascript" src="jquery.jsonp-2.2.0.min.js"></script>
<body>
<button id="boton">click me</button>
<script type="text/javascript">
$('#boton').click(function(){
$.jsonp({
url: 'http://localhost:9999',
callback: function(){},
data: {key1:'key1v',key2:'key2v'},
timeout: 50000,
success: function(){
console.log('success');
},
beforeSend: function(){console.log('fire!');}
});
});
</script>
</body>
As you can see:
- each time the button is clicked, a jsonp request is made to the
server. a log line of "fire!" is printed on browser console just before
sending the request.
- each time the server receives a request, it takes 6 seconds to send
back the response. a log line of "req received" is printed at the server's
console upon req reception. a log line of "response sent" is printed at the
server's console upon response sending
- a log line of 'success' is printed at the browser's console upon
response reception.
if I make, say 10 6 clicks in less than 6 seconds I will only see 6 "req
received" log lines. I will see 10 "fire!" loglines in the browser console
and of course no "response sent" or "success" logline whatsoever (because 6
seconds hasn't passed yet).
After the 6 seconds, the pending requests (4) comes in, and I see the 4
remaining "req received" loglines .
I guess its standard behavior, I just didn't know, I don't know if this can
be worked around somehow, or I'm just missing something.
