Force browser to clear cache

Is there a way I can put some code on my page so when someone visits a site, it clears the browser cache, so they can view the changes?

Languages used: ASP.NET, VB.NET, and of course HTML, CSS, and jQuery.

For static resources right caching would be to use query parameters with value of each deployment or file version. This will have effect of clearing cache after each deployment. 

/Content/css/Site.css?version={FileVersionNumber}

Here is ASP.NET MVC example.

<link href="@Url.Content("~/Content/Css/Reset.css")?version=@this.GetType().Assembly.GetName().Version" rel="stylesheet" type="text/css" />

Don't forget to update assembly version.

Do you want to clear the cache, or just make sure your current (changed?) page is not cached?

If the latter, it should be as simple as 

<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
