Lengthy jQuery AJAX request freezes browser

I have an AJAX request, processing of AJAX request is complex and lengthy. The problem is that this lengthy request freezes browser. I mean when AJAX request is in process then no matter if I click any link/button from page or type some Url of same website in browser address bar it does nothing and keep waiting fro AJAX request response, once AJAX response arrives back other processes start working. I am using async: true with AJAX request. Here is the code I am using. Its a simple page having nothing else but this jQuery AJAX request. My server side PHP.

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title>Test Page</title>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>
<body>
    <script type="text/javascript">
        $(document).ready(function() {
            $.ajax({
                url: 'http://www.mywebsite.com/doprocessing',
                async: true,
                success: function () {
                    alert('done');
                }
            });
        });
    </script>
</body>

Why this is happening? How can I solve this?

PS: Before you mark this duplicate, I have checked almost all similar questions on StackOverflow. No solution is working in my case (though solution in most cases was using async: true which I am already doing.

Thanks in advance,

The reason, why any of the links of the same website are not working during ajax, is that your script is locking the session in the server.

You could either not to use session for this script, or finish session after you are sure that this is correct user etc, but before starting sending emails (or doing anything else lengthy).

Use session_write_close() before starting sending emails in PHP for this.

Alternatively you can implement your own asynchronous session handler.
