Is there any Script to clear cookies on every time when the page gets loaded ?

@sTyleSHA raised a common issue: visitors often keep old copies of site assets and never see updates. As @Thirusha noted, JavaScript can read/write cookies, but clearing cookies on every page load is not a good fix — it will log users out, erase preferences, and cannot touch HttpOnly cookies set by the server. Clearing cookies is intrusive and unreliable across browsers and domains.

A safer, standard approach is cache control + asset versioning:

• Serve HTML with short/no-cache headers so the browser checks for updates.
• Serve static assets (CSS/JS/images) with long expirations but change their URLs on deploy (filename hashes or query strings) so browsers fetch the new files.
  Example HTML pattern (version token bumped at deploy):

<link rel="stylesheet" href="/css/site.css?v=1.2.3">
<script src="/js/app.js?v=1.2.3"></script>

Server-side headers example (Apache .htaccess snippet) — HTML not cached, assets cached long-term:

<IfModule mod_headers.c>
<FilesMatch ".(html|htm|php)$">
Header set Cache-Control "no-cache, must-revalidate, max-age=0"
</FilesMatch>
<FilesMatch ".(css|js|jpg|jpeg|png|gif|svg)$">
Header set Cache-Control "public, max-age=31536000"
</FilesMatch>
</IfModule>

If an automatic reload on deploy is desired, use a lightweight version-check the client can poll once and reload when the version changes (does not touch cookies):

fetch('/version.txt', { cache: 'no-store' })
.then(r => r.text())
.then(serverVer => {
const v = localStorage.getItem('siteVersion');
if (v !== serverVer) {
localStorage.setItem('siteVersion', serverVer);
location.reload();
}
})
.catch(()=>{});

Troubleshooting: confirm response headers and resource URLs in the browser DevTools Network tab, purge CDN caches after deploy, and update service worker logic if one is used. These tactics preserve user state and reliably force updated content without wiping cookies.
