Communication between two sessions with example
<p>In an asp.net application there are two different users are available. </p>

<p>When user is entered we store UserId of the user in session variable. </p>

<p>When First user sends requests to the server than server give response to first user. </p>

<p>But My question is If First user sends request then server sends request to second user like an communication between first and second user. </p>

<p>How it is possible in Asp.net? </p>
