Edge Browser caching issue

PANDIAN Kishorekumar-EXT 0

Hello All,

I have an issue in the Microsoft edge browser. we have a website. which is used by many users. when I try to access a website. The website is not showing the updated data in edge browser. But it shows the updated data in the other browsers.

It is a critical issue as the users may get affected because of using the older data. So, we have identified the issue is related to caching issue in the edge browser.

There are multiple users so, we cannot suggest the users to clear the cache. Please suggest some other solution.

Hi ,

Thank you for reaching out on Microsoft Q&A.

The issue you’re describing often occurs when Edge caches dynamic content aggressively, especially if HTTP response headers don’t specify cache-control policies. Clearing cache manually for all users can be impractical, so a more permanent solution is to configure anti-caching headers on your web server for the affected files (e.g., .php, .html, .json, or API responses).

Recommended fix Add the following headers for dynamic files on your server:

Cache-Control: no-cache, no-store, must-revalidate

Pragma: no-cache

Expires: 0

This ensures browsers fetch fresh data for dynamic content while allowing caching for static assets like .css, .js, and images for performance.

Hope this helps! If my answer was helpful, kindly follow the instructions https://learn.microsoft.com/en-us/answers/support/accept-answer so others with the same problem can benefit.

This is really a painful issue, MS should fix this on high priority, we have all the suggested steps in place, still some users on edge are facing caching issue.

We have header in place
<meta http-equiv="cache-control" content="max-age=0" /> <meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" /> <meta http-equiv="expires" content="0" /> <meta http-equiv="expires" content="Tue, 01 Jan 1980 1:00:00 GMT" /> <meta http-equiv="pragma" content="no-cache" />

we have strings at the end of the URLs
<script src="abc.0fce89fcb97107bb9542.js?v=12345" defer>
<link rel="stylesheet" href="css.d22ef0591771.css?v=12345"></head>

Still cache is not getting cleared,
