My plan is to hit an url (GET - rest) (ex: http://myserver.com/job ) every x minutes, I want to use something that could be free on the long run like a small programm running on heroku cloud.
Can I build something like that in php or java ? (both languages are supported on heroku and I have some familiarity with both)
I've tried in java so far but I don't think the multi-threading nature of it works because it gives me an error if I make any "request" logic inside a loop.
Sorry to ask such a broad question but from my search I havent found any good ideas for this problem.
SHORT ANSWER: Use IFRAME for your URL and in Javascript use setTimeout() to iterate.
DETAILED ANSWER: Modify the following source as per your needs.
(!!! https://www.disney.com is ok but some URLs may not accept IFRAME requests.)
<head>
<script charset="UTF-8" type="text/javascript" url="init.js"/>
</head>
<body onload="init()">
<form id="form1">
<iframe id="w_iframe" src="https://www.disney.com" style="left: 0px; top: 0px; width: 100%; height: 100%; position: absolute">
<p>Your browser does not support iframes.</p>
</iframe>
</form>
</body>
function init() {
var w_src = "https://www.disney.com";
document.getElementById("w_iframe").src = w_src;
setTimeout("init()", 60000); //60,000 milliseconds
}
