In ASP.NET web development, is a subdomain considered as a separate website to develop?
<p>Take a look at <a href="http://www.westpac.co.nz" rel="nofollow">http://www.westpac.co.nz</a> vs <a href="https://sec.westpac.co.nz/IOLB/Login.jsp" rel="nofollow">https://sec.westpac.co.nz/IOLB/Login.jsp</a>. You can go to the second page by clicking the login link on the first page. If you  were to develop this website in ASP.NET, do you develop 2 websites? </p>
