【正文】 atform engine. It not only only WebForms and WebServices. processing engine is also a request, access to client requests it, and then through its builtin channels, 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 pletely separate. In fact, HTTP is a runtime ponents, you can host it in IIS on the outside of the application, and even can be, and other services together. Pipeline through the use of builtin routing the request, HTTP runtime to provide a set of plex, 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 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 requests 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. is designed 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 ponent of an application39。s lifetime. introduces several new features that further enhance the deployment, management, and operations of servers. 1 Configuration API. contains new configuration management APIs, enabling users to programmatically build programs or scripts that create, read, and update and configuration files. MMC Admin Tool. provides a new prehensive admin tool that plugs into the existing IIS Administration MMC, enabling an administrator to graphically read or change mon settings within our XML configuration files. Prepilation Tool. delivers a new application deployment utility that enables both developers and administrators to prepile a dynamic application prior to deployment. This prepilation automatically identifies any pilation issues anywhere within the site, as well as enables applications to be deployed without any source being stored on the server (one can optionally remove the content of .aspx files as part of the compile phase), further protecting your intellectual property. Health Monitoring and Tracing. also provides new healthmonitoring support to enable administrators to be automatically notified when an application on a server starts to experience problems. New tracing features will enable administrators to capture runtime and request data from a production server to better diagnose issues. is delivering features that will enable developers and administrators to simplify the daytoday management and maintenance of their Web applications.
