In Normal Scenario, Response.End ends the Page Execution and thenthe excetion shifts tp Application_EndRequest.But when we Use Response.Redirect Method ,the Method shifting to Application_EndRequest does not occur because the Response.End Methodis called By the Response.Redirect Method Internally.

So the Server Does not ends its Request and A Exception is Thrown

To Avoid This,

we can use overload, Response.Redirect(String url, bool endResponse) that passes false for the endResponse parameter to suppress the internal call to Response.End So that the Response.End Explicitly called after the Response.Redirect Method To exceute and End the Process Correctly.
