The HTML meta refresh tag is most often used to redirect or reload web pages.
<br>
<br>For example, to refresh a page ever minute you would use something similiar to this:
<br>
<br>&lt;meta http-equiv=&quot;refresh&quot; content=&quot;60&quot;&gt; 
<br>
<br>This meta tag would be placed in the header of your HTML file. That is to say in the &lt;head&gt; tag.
<br>
<br>Breaking the HTML meta refresh tag down further:
<br>
<br>http-equiv=&quot;refresh&quot;
<br>This tells the web browser that this meta tag is sending an HTTP command and not a regular meta tag. Refresh is what is called a HTTP header used a web server.
<br>
<br>content=&quot;60&quot;
<br>This tells the web browser how long to wait (in seconds) before refreshing the page.
<br>
<br>The other common use for a meta refresh tag is to redirect a visitor to a new page or to another website. The format for this tag is:&lt;br&gt;
<br>
<br>&lt;meta http-equiv=&quot;refresh&quot; content=&quot;2; url=http://www.aaahtml.com/&quot;&gt; 
<br>
<br>This tells the web brower to wait 2 seconds, and then redirect to the site defined by the URL attribute.
