This is done either in the http server through the .htaccess file:<br />
<br />
Header set Cache-Control &quot;no-cache, no-store&quot;<br />
<br />
or through PHP:<br />
<br />
header('Cache-Control: no-cache, no-store');
</div>

However there is one big limitation; <b>User Settings</b>. &nbsp;<br />
<br />
You have no control over the user setting and the the browser will not refresh cache if the user settings explicitly prevent it; &nbsp;unfortunately many users have restricted cache setting to optimize response time, especially if they are on a slow connection or use a lot of sites heavy on graphics or videos.<br />

The solution Dave offers is a commonly used approach. &nbsp;You can just add the version number to the new file. &nbsp;The only drawback the approach has is if you are delivering static pages with the file names hard-coded; in which case you will need to change the file name on every page.<br />

My website is looking different in different websites. Any update on CSS is not reflecting immediately in firefox but where as safari and chrome show the modification immediately.<br />
Is there a way to add a code which clears the existing cache whenever the website loads and uses the latest style sheet.

Cascading Style Sheets (CSS) is a language used for describing the look and formatting of a document written in a markup language. Usually used to change web pages and user interfaces written in HTML, it can also be applied to any kind of XML document. CSS is designed primarily to distinguish the content of a document from its presentation.

A scripting language is a programming language that supports scripts, programs written for a special run-time environment that automate the execution of tasks that could alternatively be executed one-by-one by a human operator. Scripting languages are often interpreted (rather than compiled). Primitives are usually the elementary tasks or API calls, and the language allows them to be combined into more complex programs. Environments that can be automated through scripting include software applications, web pages within a web browser, the shells of operating systems (OS), embedded systems, as well as numerous games. A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, this is also known as an extension language.
