If you write the second parameter as true than it will throw an exception
i.e.
System.Threading.ThreadAbortException: Thread was being aborted.
because the running thread is ended and trying for another thread.
and if you write false than it will not show any exception.
Response.Redirect("page_name.aspx",true)<--Throw Exception.
Response.Redirect("page_name.aspx",false)<--Exception Free.
