ASP.NET asynchronous stored procedure

I have a method that calls a long running sp from an ASP.NET page.  What I want to be able to do is start executing the sp, and continue with any other statments that may need to be executed in the page.  I also require the sp to continue running even after the web app closes.  I don't need any results returned to the web page as I'm writing to a table in the database on completion.

What would be the best way to handle this.

Including the code that calls the sp.

Dim retValue As Integer = 0

            Using connection As New SqlClient.SqlConnection(connectString)
                Dim command As SqlClient.SqlCommand = connection.CreateCommand

                command.CommandType = CommandType.StoredProcedure
                command.CommandText = "LongProcess"
                command.CommandTimeout = 18000 ' 5 hours

                command.Parameters.Add("@Descrip", SqlDbType.VarChar).Value = descrip

                    retValue = command.ExecuteNonQuery

                Catch ex As Exception
                    Throw ex
                End Try
            End Using
            Return retValue
        End Function
