If you want internet browsers to recognise your XML/RSS feeds as soon as a visitor reaches your website, then this article is for you. Browsers such as Internet Explorer 7 have XML/RSS functionality built in and you can make the most of this by enabling the feed button on the toolbar. To do this, all you need to do is add the below line of code in between the head tags of your web page/s.
<link rel="alternate" type="application/rss+xml" title="RSS Feed Title" href="link_to_your_xml_or_rss_feed" />
An example of this is
<head> <link rel="alternate" type="application/rss+xml" title="News Feed" href="rss.aspx" /> </head>
