Question

I have a dumb network device that has limited HTTP hosting capabilities and I’m trying to write a slightly more dynamic page to display data with. A some current process values can be found in plain-text at /temp.dat on the device, but my stone-simple jQuery script…

$(document).ready(function() {
     $('#temp').load('/temp.dat');
   var refreshId = setInterval(function() {
      $('#temp').load('/temp.dat');
   }, 2000);
   $.ajaxSetup({ cache: false });
});

…seems to endlessly fail (only after the first .load on the initial page load) because the device abhors HTML query parameters. Chrome’s JS console shows endless errors like the following:

GET http://192.168.1.250/temp.dat?_=1341980712854  

How can I get jQuery (or pure JavaScript) to hammer away at a specific URL without attaching the HTML query (…?_=123456789)?

Answer 1

You should be able to add this at the top of the script

$.ajaxSetup ({
    cache: true
});
