Definition of ONE asp.net application? 
<p>How do you define <strong>ONE</strong> asp.net application? Does it have to be built under one solution or does it have to be deployed under one application under IIS? </p>

<p>Can multiple web projects be deployed under one IIS application (so that they have access to each other's session, cache etc) ?</p>

<p>This is just a theoretical question.</p>

<p><strong>Update:</strong> What I am stressing on is what makes it <strong>ONE</strong> application. </p>
