How does an Interface implement functionality?
<p>In ASP.net Generic handler files (.ashx)
Sessions are by default not enabled, the sessions collection is empty no matter what.</p>

<p>But by simply implementing the "ISessionHandler", sessions are suddenly accessable though the sessions collection..</p>

<p>I really dont understand that, becuase in my head interfaces doesnt do anything other than telling other stuff what methods, properties etc. it needs to have.</p>

<p>Does anyone know how that works?</p>

<p>Thanks in advance :)</p>
