I want to submit a form including a header during posting the request , is that possible ? I tried below code but I was unable to send the request with the defined header .
<html>
<body>
<script>
var xhr = new XMLHttpRequest;
xhr.setRequestHeader("Myheader" , "value")
</script>
<form action="https://example.com/myprofile/myedit" method="POST">
<input type="hidden" name="firstname" value="Jacob " />
<input type="hidden" name="email" value="jacob@gmail.com" />
<input type="submit" value="Submit request" />
</form>
</body>
</html>

No.
You can only add custom HTTP headers to a request if you are using XMLHttpRequest or fetch to make the request (so you can't if you are using a form submission to make the request).
You could use the submit event to intercept the form submission and make the request with XMLHttpRequest or fetch instead … but then you'd need to handle the response with JS too.
