31.Differentiate globalization and localization.
The globalization is a technique to identify the specific part of a Web application that is different for different languages and make separate that portion from the core of the Web application. The localization is a procedure of configuring a Web application to be supported for a specific language or locale.
32.What is a Cookie? Where is it used in ASP.NET?
Cookie is a lightweight executable program, which the server posts to client machines. Cookies store the identity of a user at the first visit of the Web site and validate them later on the next visits for their authenticity. The values of a cookie can be transferred between the user’s request and the server’s response.
33.What is the default timeout for a Cookie?
The default time duration for a Cookie is 30 minutes.
34.How does a content page differ from a master page?
A content page does not have complete HTML source code; whereas a master page has complete HTML source code inside its source file.
35.Explain how Cookies work. Give an example of Cookie abuse.
The server tells the browser to put some files in a cookie, and the client then sends all the cookies for the domain in each request. An example of cookie abuse is large cookies affecting the network traffic.
36.What are the advantages of the code-behind feature?
The code-behind feature of ASP.NET offers a number of advantages:
- Makes code easy to understand and debug by separating application logic from HTML tags
- Provides the isolation of effort between graphic designers and software engineers
- Removes the problems of browser incompatibility by providing code files to exist on the Web server and supporting Web pages to be compiled on demand.
37.What is an ASP.NET Web Form?
ASP.NET Web forms are designed to use controls and features that are almost as powerful as the ones used with Windows forms, and so they are called as Web forms. The Web form uses a server-side object model that allows you to create functional controls, which are executed on the server and are rendered as HTML on the client. The attribute, runat=”server”, associated with a server control indicates that the Web form must be processed on the server.
38.What is IIS? Why is it used?
Internet Information Services (IIS) is created by Microsoft to provide Internet-based services to ASP.NET Web applications. It makes your computer to work as a Web server and provides the functionality to develop and deploy Web applications on the server. IIS handles the request and response cycle on the Web server. It also offers the services of SMTP and FrontPage server extensions. The SMTP is used to send emails and use FrontPage server extensions to get the dynamic features of IIS, such as form handler.
39.What is Query String? What are its advantages and limitations?
The Query String helps in sending the page information to the server.
The Query String has the following advantages:
- Every browser works with Query Strings.
- It does not require server resources and so does not exert any kind of burden on the server.
The following are the limitations of Query String:
- Information must be within the limit because URL does not support many characters.
- Information is clearly visible to the user, which leads to security threats.
40.What is the difference between authentication and authorization?
Authentication verifies the identity of a user and authorization is a process where you can check whether or not the identity has access rights to the system. In other words, you can say that authentication is a procedure of getting some credentials from the users and verify the user’s identity against those credentials.
Authorization is a procedure of granting access of particular resources to an authenticated user. You should note that authentication always takes place before authorization.
