Prevent Index.html from being stored in cache

Currently, Index.html contains numerous JavaScript files that are concatenated and minified into a single file. This consolidated file undergoes a name change due to the filerev grunt task.

Although this process functions correctly, an issue arises when Index.html is cached, causing it to reference old JS file names after a new deployment. How can we ensure that Index.html always retrieves the latest version from the server? Alternatively, how can we implement regular checks every 15 minutes for updates?

Appreciate any guidance on this matter.

Answer №1

To handle these matters, typically they are controlled on the webserver. However, a quick solution involves inserting these meta tags in your header:

<meta http-equiv="cache-control" content="max-age=0" />
<meta http-equiv="cache-control" content="no-cache" />
<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" />
