HTML and JavaScript Redirection
1. Simple HTML + JavaScript Redirect
This method uses both HTML meta tags and JavaScript for immediate redirection.
<!DOCTYPE HTML>
<html lang="en-US">
<head>
<meta charset="UTF-8">
<meta http-equiv="refresh" content="0; url=https://netnaps.com">
<script type="text/javascript">
window.location.href = "https://netnaps.com";
</script>
<title>Redirecting to Netnaps.com</title>
</head>
<body>
<!-- Fallback for Non-JavaScript Users -->
If you are not redirected automatically, follow this <a href='https://netnaps.com'>link to NETNAPS</a>.
</body>
</html>2. JavaScript Fallback for Non-JavaScript Users
This snippet ensures redirection even if JavaScript is disabled.
<script>
window.location.replace("https://netnaps.com");
</script>
<noscript>
<a href="https://netnaps.com">Click here if you are not redirected automatically.</a>
</noscript>3. Delayed Redirection with Meta Tag
Use this for a delayed redirect (e.g., 5 seconds).
<meta http-equiv="refresh" content="5; url=https://netnaps.com/" />4. INIT Function with HTML Redirection
This method uses JavaScript’s onload event to trigger redirection.
<!DOCTYPE html>
<html>
<head>
<title>Redirect Example</title>
<script>
function init() {
window.location.href = "https://netnaps.com";
}
