I created an HTML file to obtain a file that will update data every minute.
I had tried <meta http-equiv="refresh" content="60"> function but it doesn't show the latest data.
If I press CTRL + F5 manually, the page will update the latest data.
How do I perform a hard refresh instead of normal refresh in HTML by using <meta http-equiv="refresh" content="60">?
Update
I found the issue, is it because my source file(xml file) is getting the same data.
After I change the
xmlhttp.open("GET", "merged_.xml, true); to
xmlhttp.open("GET", "merged_.xml?id="+Math.random(), true);
The source file will update to the latest data.
