You create an ASP.NET application to provide online order processing to XYZ customers.
A page named ShippingInformation.aspx contains a Web Form with controls for collecting
shipping location information. The Web Form contains the following elements:
• Four TextBox controls for entry of name, street address, city, and postal code.
• A DropDownList control that consists of the full names of 150 countries.
• A Button control named shipItButton.
The Click event handler for shipItButton is located in the code-behind file for
ShippingInformation.aspx. None of the other controls on the Web Form define server-side event
handlers.
The Click event handler for ShipItButton redirects the user to a page named
ShippingConfirmation.aspx. The ShippingConfirmation.aspx page provides the confirmation
status of the shipping request submission to the user.
Users who access the application by using dial-up connections report that
ShippingInformation.aspx processes very slow after the user clicks the shipItButton. Users on
high-bandwidth network connections do not report the same issue.
You need to decrease the delay experienced by the dial-up users. What should you do?
A. Add the following attribute to the Page directive for ShippingInformation.aspx:
EnableViewState=”False”
B. Add the following attribute to the Page directive for ShippingInformation.aspx:
SmartNavigation=”True”
C. Add the following attribute to the OutputCache directive for ShippingInformation.aspx:
Location=”server”
D. Add the following attribute to the OutputCache directive for ShippingInformation.aspx.
Location=”client”
