b) Webservice proxies.
Answer: A client and a Web service can communicate using SOAP messages, which encapsulate the
input and output parameters as XML. A proxy class maps parameters to XML elements and then sends
the SOAP messages over a network. In this way, the proxy class frees you from having to communicate

2. with the Web service at the SOAP level and allows you to invoke Web service methods in any

3 Describe about IIS RequestProcessingModelsand IIS services.
Answer: Worker process isolation mode is the new IIS request processing model. In this application
isolation mode, you can group Web applications into application pools, through which you can apply
configuration settings to the worker processes that service those applications. An application pool

4 Discuss the following:
a) Forms Authentication
Answer: Forms authentication lets you authenticate users by using your own code and then maintain an
authentication token in a cookie or in the page URL. Forms authentication participates in the ASP.NET
page life cycle through the Forms Authentication Module class. You can access forms authentication
informationandcapabilitiesthroughthe FormsAuthenticationclass.
To use forms authentication, you create a login page that collects credentials from the user and that

variables of other types, methods and events. A class is like a blueprint. It defines the data and behavior
of a type. If the class is not declared as static, client code can use it by creating objects or instances
