How to clear cache in Sitecore

Question

I updated the RichText commands.js file under /sitecore/shell/controls/rich text editor .

I have copied it to the production environment, but my change isn't being applied. I am guessing JS is cached - how do I clear the cache? Site doesn't require a publish since content items weren't updated. Cleared the cache at /sitecore/admin/cache.aspx too.

Browser caching cleared. Recycled the app pool and restarted the website as well.

Sitecore 7.2

Answer 1

The javascript is cached in your browser not in Sitecore. Depending on your browser you can clear it from the toolbox (all of them have a clear cache option) or use the following shortcuts:

Firefox, Chrome, IE: Ctrl+Shift+Delete
Safari: Ctrl+Alt+E

Answer 2

This is a browser caching. A common solution is to add a ? to the script's src link.

For instance: you can modify

 Website\sitecore\shell\Controls\Rich Text Editor\Default.aspx

and

\Website\sitecore\shell\Controls\Rich Text Editor\EditorPage.aspx

to have:

<script type="text/javascript" language="javascript" src="/sitecore/shell/Controls/Rich Text Editor/RichText Commands.js?v=152605"></script>

Also you can open your browser in incognito mode or to delete browser cache
