Module 15: Configuring, Optimizing, and Deploying a Microsoft ASP.NET Web Application

1. Module 15:Configuring, Optimizing, and Deploying a Microsoft ASP.NET Web Application

2. Overview • Using the Cache Object • Using ASP.NET Output Caching • Configuring an ASP.NET Web Application • Deploying an ASP.NET Web Application

3. Lesson: Using the Cache Object • What Is the Cache Object? • Advantages of Using the Cache Object • How to Use the Cache Object • Removing Items from the Cache Object • Demonstration: Using the Cache Object

4. What Is the Cache Object? • An object used to store information • One Cache object per Web Application • An alternative to application variables • Not used to store information in session variables • Uses key-value pairs to store and retrieve items Cache("myKey") = myValue Cache["myKey"] = myValue;

5. Advantages of Using the Cache Object • Faster than creating a new object for each request • Supports internal locking • Automatic cache resource management • Supports callback functions • Supports removal based on dependencies

6. How to Use the Cache Object • Writing to the Cache object: • Retrieving values from the Cache object: 'Implicit method Cache("myKey") = myValue 'Explicit method Cache.Insert("myKey", myValue, Dependency, AbsoluteExpiration, _ SlidingExpiration, CacheItemPriority, CacheItemRemovedCallBack) //Implicit method Cache["myKey"] = myValue; //Explicit method Cache.Insert("myKey", myValue, Dependency, AbsoluteExpiration, SlidingExpiration, CacheItemPriority, CacheItemRemovedCallBack); myValue = Cache("myKey") myValue = Cache["myKey"];

7. Removing Items from the Cache Object • AbsoluteExpiration time • SlidingExpiration time • Dependent on a changed value • Cache item priority DateTime.Now.AddMinutes(5) TimeSpan.FromSeconds(20) AddCacheItemDependency("Variable.Value") CacheItemPriority.High

8. Demonstration: Using the Cache Object • Run the CacheTest.aspx page without the Cache object enabled • Run the CacheTest.aspx page with the Cache object enabled • Run the CacheTest.aspx page with the Cache object enabled and with a dependency

9. Lesson: Using ASP.NET Output Caching • Multimedia: Output Caching • Output Cache Types • How to Use Page Output Caches • Demonstration: Page Output Caching • How to Use Fragment Caching

10. Multimedia: Output Caching

11. Output Cache Types • Page caching • Page fragment caching as a user control • XML Web service caching

12. How to Use Page Output Caches • Cache content is generated from dynamic pages • Entire Web page is available in cache • Set cache duration in seconds • Set the VaryByParam property to control the number of page variations in the cache <%@ OutputCache Duration="900" VaryByParam="none" %>

13. Demonstration: Page Output Caching • Show how a page that does not cache changes with each refresh • Show how a page that caches does not change with each refresh • Show how changing a parameter can cause a new page to be cached

14. How to Use Fragment Caching • Convert the page fragment into a user control • Set the Duration and varyByParam properties <%@ OutputCache Duration="120" VaryByParam="none" %>

15. Lesson: Configuring an ASP.NET Web Application • Overview of Configuration Methods • Configuring a Web Server Using Machine.config • Configuring an Application Using Web.config • Understanding Configuration Inheritance • Demonstration: Configuration Inheritance • Practice: Determining Configuration Inheritance • Storing and Retrieving Data in Web.config • Using Dynamic Properties • Demonstration: Using Dynamic Properties

16. Overview of Configuration Methods • Machine.config file • Machine-level settings • Web.config files • Application and directory-level settings • Both Machine.config and Web.config files are: • Well-formed XML • camelCase • Extendable

17. Configuring a Web Server Using Machine.config • Settings in the Machine.config file affect all Web applications on the server • Only one Machine.config file per Web server • Most settings can be overridden at the application level using Web.config files

18. Configuring an Application Using Web.config • One or more Web.config files per Web application • All configuration information for the application is contained in the Web.config files • Contains a section for each major category of ASP.NET functionality • Security • Mode • General application settings • Tracing

19. Understanding Configuration Inheritance • Application-level Web.config file inherits settings from Machine.config file • Settings in Web.config file that conflict override inherited settings • Individual directories may have Web.config files that inherit from—and can override—application-level settings CONFIG Machine.config VirtualDir Web.config SubDir Web.config

20. Demonstration: Configuration Inheritance • Create a subfolder that contains a Web.config file • Show differences between the main Web.config file and the subfolder's Web.config file • Demonstrate how the Web Form reads information from the Web.config files • Delete the Web.config file from the subfolder and refresh the Web Form

21. Practice: Determining Configuration Inheritance • Students will: • Determine the configuration settings for a Web application based on several variables • Time: 5 Minutes

22. Storing and Retrieving Data in Web.config • Storing application settings in a Web.config file • Retrieving application settings from a Web.config file <configuration> <appSettings> <add key="pubs" value="server=localhost; integrated security=true; database=pubs"/> </appSettings> </configuration> Dim strPubs As String = _ ConfigurationSettings.AppSettings("pubs") AppSettingsReader App = new AppSettingsReader(); string strPubs = (string)App.GetValue("pubs", typeof(string));

23. Using Dynamic Properties • Store property values in Web.config files rather than in the application's compiled code • Allows easy updates without recompiling the application • Enable and configure through object properties

24. Demonstration: Using Dynamic Properties • Configure a SqlConnection object to use dynamic properties • Show the newly generated code in the code-behind page • Open Web.config file and show the SqlConnection1.ConnectionString key in the appSettings section

25. Lesson: Deploying an ASP.NET Web Application • Web Application Deployment • Preparing a Web Application for Deployment • Practice: Selecting Necessary Files • Sharing Assemblies in the Global Assembly Cache • Updating Your Web Application

26. Web Application Deployment • Copy files locally or FTP files remotely • Configure the target folder as a virtual directory in IIS • Copy all necessary files, including the \bin directory and content • No need to register components

27. Preparing a Web Application for Deployment • Build the Web application • Do not select unnecessary files • Visual Studio .NET solution files (.vbproj, .vbproj.webinfo, .csproj, .csproj.webinfo, etc.) • Resource (.resx) files • Code-behind pages (.vb, .cs) • Copy or FTP necessary files to the production directory

28. Practice: Selecting Necessary Files • Students will: • Select the files necessary for a deployment • Time: 5 Minutes

29. Sharing Assemblies in the Global Assembly Cache • The global assembly cache provides storage for assemblies you need to share • Machine-wide cache for code • Because DLL files are not registered, they are not easily shared between Web applications

30. Updating Your Web Application • Copy or FTP files to update the Web application • Do not need to stop and restart IIS • .dll files can be updated while the site is still running • Output cache protects existing users

31. Review • Using the Cache Object • Using ASP.NET Output Caching • Configuring an ASP.NET Web Application • Deploying an ASP.NET Web Application
