How to create Google blogger type Sub Domain URL for blog
<p>I have to create a BLOG section in my website. If my site is www.abc.com, then I have to create different blogs like  google blogger service.</p>

<p><a href="http://author1.abc.com" rel="nofollow">http://author1.abc.com</a></p>

<p><a href="http://author2.abc.com" rel="nofollow">http://author2.abc.com</a></p>

<p>I have the ability to create unlimited sub domains but I am not able to understand how above blog URL will work. These will be virtual sub domains or will I have to create actual sub domains.
Is it possible via Url rewriting? If yes, how?</p>

<p>If I use Url rewriting, browser will redirect the above URL to page for which I have craeted the URL rewriting rule. I dont want to change the URL in browser.</p>

<p>Any one has any suggestion?</p>
