Unfortunately, your regular users will probably not see any updates because their browser will still use the old and cached versions. And you cannot control remotely the Ctrl + F5 shortcut…
To avoid this, there is a simple trick of “versioning” your files by adding a different prefix for each new version. Generally, a version number is used, for example:
<link rel="stylesheet" href="/css/style.css" type="text/css" media="all"/>
<link rel="stylesheet" href="/css/style.css?ver=1.1" type="text/css" media="all"/>
With this change of URL, the browser thinks it is a new file and will reload it.
