In PHP, we can use the header() function to redirect the URL.
In HTML, we can use the meta tag to redirect the URL.
For more information, visit PHP/HTML – Redirect URL in Seconds
But sometimes, we want the redirection starts after the HTML body is loaded. This can be done by Javascript.
<html>
<head>
</head>
<body>
<h1>Eureka!</h1>
<script type="text/javascript">
alert("Going to Eureka!");
window.location= "https://ykyuen.wordpress.com/";
</script>
</body>
</html>
Done =)
Reference: Redirect AFTER Headers
Eureka!
