The final step after designing and developing your Web Forms and web application is to complete your ASPNET web application by deploying the application to the production server that is going to respond to the client requests The term deploy is used to encompass the optimization and configuration of the web application, the planning of how and what to install on the production server, and the installation of the web application on the production server The deployment process also includes configuration of the web application by setting up the security for the web application as well as optimizing the response time for the web application by configuring Cache objects The configuration of the web application is performed by modifying the content of the web applications configuration file The configuration settings are stored in text files that must be organized to support and secure the ASPNET web application The deployment questions of the exam focus on the configuration files The last topic in the chapter is the issue of installing and configuring the IIS web server and FrontPage extensions These topics are not exactly in the developer realm, but they are listed as potential areas that can be queried in the exam

In this section, we will look at the four steps that are part of the deployment of an ASPNET web application The following steps are part of all deployments: Caching and performance configuring the Cache object Configuring the web application optimizing the configuration files Securing the web application edit the configuration Deploying the web application selecting and copying the files for deployment to the production server The planning for deployment centers around performance and security, and it is driven by the need to achieve good performance (good response time) and the security policy in place at the site We will start with the performance issues

This technique involves tricking people into revealing their passwords or some form of security information A Network spoofing B Data mining C Social engineering D Password cracking

FIGURE 1116:

The performance of an ASPNET web application is most easily increased by using the ASPNET Cache object ASPNET offers two types of caches: the Cache object that is used to cache items such as the result of a computation, and the output cache that can be used to store web pages and controls The theory behind a cache is that if you store frequently needed items in local memory, you can retrieve those items more quickly than if you had to retrieve those same items from the hard disk or re-create them with a computation The two types of caches that are supplied are used in different roles in an ASPNET web application By using the Cache object, you can place objects in the memory of the server The Cache object is provided in ASPNET to provide programmable caching through an object that gives us full control of the caching process including the dependency between cached objects and the life span of the cached object each ASPNET web application has one Cache object You store one copy of the item in memory the first time that item is accessed, and after that the item is read from the Cache object every time it is requested this eliminates the duplication of items in the Cache object Using the cached copy of the item also minimizes work duplication for the server and increases performance The output cache is more like a traditional cache on a web server using the output cache we can keep web pages or even portions of web pages in the output cache for faster retrieval of that information

The Cache object uses references to the items (objects) it stores, and provides the process (business rules) to track the item s policy (expiration and dependency) One of the features of the Cache object is that it provides a method for web pages in the ASPNET web application to pass values between each other

97 Budget proposals are not critical information, as they eventually do become public knowledge A True B False

EXAM TIP The Cache object can be used to pass values between web pages in the same ASPNET web application The developer configures a web page to request that an item be stored in the Cache object To save an item in the Cache object, the web page needs to specify a key-value pair The key is what the Cache object uses to reference the item by, and the value is the information to be cached Keys are arbitrary strings that you define The following code segment shows how you can store an item in the Cache object:

Cache["theKey"] = theValue;

To retrieve an item from the Cache object, you use this syntax:

Threats to information could include: A Being copied B Being stolen C Being destroyed D All of the above

theValue = Cache["theKey"];
