We are getting a weird issue on which we are not sure what exactly

We are getting a weird issue on which we are not sure what exactly cause it. Let me elaborate the issue. Suppose, we have two different html pages a.html and b.html. And a little script written in index.html:

<html>

<head>
    <script>
    function reloadFrame(iframe, src) {
        iframe.src = src;
    }
    </script>
</head>

<body>
    <form>
        <iframe id="myFrame"></iframe>
        <input type="button" value="Load a.html" onclick="reloadFrame(document.getElementById('myFrame'), 'a.html')">
        <input type="button" value="Load b.html" onclick="reloadFrame(document.getElementById('myFrame'), 'b.html')">
    </form>
</body>

</html>

A server component is continuously updating both files a.html and b.html. The problem is the content of both files are successfully updating on the server side. If we open we can see the updated changes but client getting the older content which doesn’t show the updated changes.

Any idea?

    Add this in a.html and b.html

    <head>
    <meta http-Equiv="Cache-Control" Content="no-cache" />
    <meta http-Equiv="Pragma" Content="no-cache" />
    <meta http-Equiv="Expires" Content="0" />
</head>

    To force no cache checks
