Browser sends multiple request 5 to 10 request in a second withoutuser action

Our application is created in C#, ASP.Net 2.0, SQL 2005; the session
is managed in SQL server with ASPState. We often file below exception

Error Details :

Exception of type 'System.Web.HttpException' was thrown.

The wondering thing here is these exceptions are just flooding in from
the cleint while they request the application via browser and time it
go on and on for 30 minutes, please do any one has any clue or faced
such issue in past, we were looking at the solution but not able to
find any.

Thanks in advance.
