1、附录 1：外文文献原文ASP.NETASP.NET ArchitectureArchitecture1 1ASP.NET is fully managed code to deal with the use of Web request for a mature platform engine. It not only only WebForms and WebServices. ASP.NET processing engine is also a request, access to client requests it, and then through its built-in cha
2、nnels, the request to an end, in the end, developers can add logic to deal with this request code. In fact the engine and HTTP or Web Server is completely separate. In fact, HTTP is a run-time components, you can host it in IIS on the outside of the application, and even can be, and other services t
3、ogether.Pipeline through the use of built-in routing the request, HTTP runtime to provide a set of complex, but very elegant mechanism. In dealing with every aspect of the request are a lot of objects, but the majority of objects or events can be derived from the expansion interface. Therefore, this
4、 framework has a very high scalability. A mechanism through which to enter a lower level interface, such as: caching, authentication, authorization, such as is possible. You can process the request before or after the content filtering, or simply to match the signature of the designated client reque
5、sts directly to your router or to other code in the URL. For the same thing can be dealt with through different methods, and the realization of the code are very intuitive. In addition, between the easy development and performance, HTTP operation was to provide the best flexibility. ASP.NET 2.0 is d
6、esigned with administration and manageability in mind. We recognize that while simplifying the development experience is important, deployment and maintenance in a production environment is also a key component of an applications lifetime. ASP.NET 2.0 introduces several new features that further enh
7、ance the deployment, management, and operations of ASP.NET servers. 1 http:/ API. ASP.NET 2.0 contains new configuration management APIs, enabling users to programmatically build programs or scripts that create, read, and update Web.config and machine.config configuration files. ASP.NET MMC Admin To
8、ol. ASP.NET 2.0 provides a new comprehensive admin tool that plugs into the existing IIS Administration MMC, enabling an administrator to graphically read or change common settings within our XML configuration files.Pre-compilation Tool. ASP.NET 2.0 delivers a new application deployment utility that
9、 enables both developers and administrators to precompile a dynamic ASP.NET application prior to deployment. This precompilation automatically identifies any compilation issues anywhere within the site, as well as enables ASP.NET applications to be deployed without any source being stored on the ser
10、ver (one can optionally remove the content of .aspx files as part of the compile phase), further protecting your intellectual property. Health Monitoring and Tracing. ASP.NET 2.0 also provides new health-monitoring support to enable administrators to be automatically notified when an application on
11、a server starts to experience problems. New tracing features will enable administrators to capture run-time and request data from a production server to better diagnose issues. ASP.NET 2.0 is delivering features that will enable developers and administrators to simplify the day-to-day management and
12、 maintenance of their Web applications. Flexible ExtensibilityASP.NET 2.0 is a well-factored and open system, where any component can be easily replaced with a custom implementation. Whether it is server controls, page handlers, compilation, or core application services, youll find that all are easi
13、ly customizable and replaceable to tailor to your needs. Developers can plug in custom code anywhere in the page lifecycle to further customize ASP.NET 2.0 to their needs. Server Control Extensibility. ASP.NET 2.0 includes improved support for control extensibility, such as more base classes that en
14、capsulate common behaviors, improved designer support, more APIs for interacting with client-side script, metadata-driven support for new features like themes and accessibility verification, better state management, and more. Data Source Controls. Data access in ASP.NET 2.0 is now performed declarat
15、ively using data source controls on a page. In this model, support for new data backend storage providers can be easily added by implementing custom data source controls. Additionally, the SqlDataSource control that ships in the box has built-in support for any ADO.NET managed provider that implemen
16、ts the new provider factory model in ADO.NET.Compilation Build Providers. Dynamic compilation in ASP.NET 2.0 is now handled by extensible compilation build providers, which associate a particular file extension with a handler that knows how to compile that extension dynamically at runtime. For example, .resx files can be dynamically compiled to resources, .wsdl files to web service proxies, and .xsd files to typed DataSet obje
