For this you can make use of Server Side state Management Techniques and Application Life Cycle Events in Global.asax file of your application: First of all create Page saying Server is too busy or any other mesage of your choice you want to display: Now implemet the following functionality in your Gloabl.asax file void Application_Start(object sender EventArgs e) { Application[ActiveUsers] = 0; Application[AllowedUsers] = 100; } void Session_Start(object sender EventArgs e) { try { // Locking here is done to keep the things Synchornized Application.Lock(); if ( Convert.ToInt32(Application[ActiveUsers ]) Convert.ToInt32(Application[ AllowedUsers ]) ) { Response.Redirect(  true); } else { Although this will also become part of your Application because first it is coming to your application and then getting redirect but cannot access your application so anyway you can keep the traffic low by showing only this message page Application[ActiveUsers] = Convert.ToInt32(Application[ActiveUsers ]) + 1 ; } } finally { Application.UnLock(); } } void Session_End(object sender EventArgs e) { Application.Lock(); Application[ActiveUsers] = Convert.ToInt32(Application[ActiveUsers ]) - 1 ; Application.UnLock(); } Regards AJ
