【正文】 e, so its speed is very fast. But for enterpriselevel development is very difficult to administer. Therefore, in a certain period of time, ISAPI mainly serve as a platform for other applications or the bridge interface. But in any case, ISAPI has not been abandoned. In fact, the Microsoft platform and the interface is through the IIS host. NET in the ISAPI extension to munication, and then runtime direct access to . ISAPI provides the core Web Server munication interface, and then use nonmanaged code request access to and issued in response to client requests. ISAPI provides the content object is similar to the public through the HttpRequest and HttpResponse, through a well designed, accessible interface, the way to managed objects exposed to nonhosted data. From the browser to the Let us start with a typical Web request lifecycle starting point. Users to type in the browser a URL, click on a hyperlink, to submit a HTML form a post request , or a client program calls the WebService through to provide services . The server side, IIS5 or IIS6 will receive the request. The bottom of and IIS through ISAPI extension of munication, and then through the , the request is usually with a route. Aspx page extensions. However, the process of how the work is entirely dependent on the HTTP processor handler implementation. The processor will be installed to handle the specified extension. In the IIS in,. Aspx by the extended application has been mapped to the ISAPI the dll file: . A trigger for each request, must be registered by a, and point to the extension to identify.? Note: ISAPI is a custom Web request and deal with the first performance of IIS with the highest point of entry.? Rely on the extension, routing a request to an appropriate processor, which is responsible for dealing with this request. For example, WebServices extension. Asmx not routing a request to a disk page, but will be routed to in the definition of the specified characteristics of the additional WebMethodAttribute class, the characteristics of its logo will be into a Web Services implementation. Many other processors will be installed in conjunction with . Of course, we can define your own processor. In all the HttpHandler in IIS is mapped to ISAPI and expansion, and these are in the HttpHandler in configuration for routing the request to a specific processor in the implementation of HTTP. Each processor is a. NET class to handle the specified extension. These processors can handle only a few simple lines of code to the Hello World, also similar to handle plex pages as well as the implementation of WebService. For now, just need to understand the expansion of the mapping is a basic mechanism, can use it to obtain a request in ISAPI, and then routing the request to a specific request to deal with the processor.? ISAPI connection? ISAPI is the underlying unmanaged Win32 API. It defines a single interface and is the optimal performance. To deal with the original use of the interface pointer raw pointer , and a list of function pointer function pointer tables are used for callback. ISAPI provides the lowest stratum, highperformance interface, tool developers and vendors can use these interfaces to the IIS indepth. ISAPI is very low as a result, therefore, less suitable to use it to build applicationlevel procedures. ISAPI tend to be used as a bridge interface for highlevel tools to provide the function of the type of application services. For example, ASP and are as cold fusion cold fusion to build on top of the ISAPI. Most of Perl, PHP and JSP as the implementation of a number of thirdparty solutions, can be run in IIS. ISAPI is a very good tool for highlevel applications to provide a highperformance vertical access interface. This makes those highlevel application requires information from the ISAPI extract the information provided. In ASP and , the engine can be extracted ISAPI interface object, such as in the form: Request and Response, these objects can request information from the ISAPI read their content.? As agreed, ISAPI support ISAPI extension of extensions and the ISAPI filter filters . Request for expansion is to deal with interface with the Web Server to provide the input and outputrelated logic to deal with. In essence, it is a Service interface. ASP and are to achieve as ISAPI extension. ISAPI is the hook interface, it allows you to see into the IIS request and every request can be amended including the input and output or to change the module such as: authentication, etc. behavior. Incidentally, through two aspects: HTTP processor corresponding ISAPI extension and the HTTP module ISAPI filter counterpart is mapped to the ISAPI. 附錄 2：外文文獻中文譯文 通過使用內(nèi)置的管道路由請求， HTTP 運行時提供了一套復(fù)雜的，但卻很優(yōu)雅的機制。在處理請求的每一個層面都牽涉到許多對象，但大多數(shù)對象都可以通過派生或者事件接口來擴展。所以，此框架具有非常高的可擴展性。通過這一套機制，可以進入較低層次的接口如：緩存，身份驗證，授權(quán)等是有可能的。你可以在處理請求之前或之后過濾內(nèi)容，或者僅僅把匹配指定簽名的客戶端請求直接路由到你的代碼里或轉(zhuǎn)向其它的 URL。針 對同一件事情，可以通過不同的處理方法完成，而且實現(xiàn)代碼都非常的直觀。除此之外，在容易開發(fā)和性能之間， HTTP運行時還提供了最佳的靈活性。 是設(shè)計與管理性和可管理性，在銘記。我們認識到，同時簡化的發(fā)展經(jīng)驗是很重要的，部署和維護在生產(chǎn)環(huán)境中，也是一個關(guān)鍵組成部分，一個應(yīng)用程序的壽命。 介紹了幾種新功能，進一步加強部署，管理和運作服務(wù)器。 配置的空氣污染指數(shù)。 中包含新的配置管理 API ，使用戶以編程方式建立的程序或腳本創(chuàng)建，讀取和更新的 和 中配置文件。 的 MMC 管理工具。 提供了一種新的綜合管理工具，插入現(xiàn)有的 IIS 管理 MMC 中，使管理員能夠生動地讀取或改變共同設(shè)置在我們的 XML 配置文件。 前匯編工具。 提供了一個新的應(yīng)用程序部署實用工具，使雙方開發(fā)人員和管理員，以 prepile 一個動態(tài)的應(yīng)用在部署之前。這 prepilation自動識別任何匯編的問題，任何地方的網(wǎng)站，以及使應(yīng)用程序?qū)⒁渴饹]有任何來源的被存儲在服務(wù)器上（一可以選擇性地刪除的內(nèi)容的。 aspx 文件的一部分，該編譯階段） ，進一步保護您的知識 產(chǎn)權(quán)。 健康監(jiān)測和追蹤。 也提供了新的健康監(jiān)測的支持，以使管理員能夠自動通知申請時，在服務(wù)器上開始遇到問題。新的追蹤功能，將讓管理者能捕獲的運行時間和請求，將數(shù)據(jù)從生產(chǎn)服務(wù)器，以更好地診斷問題。 提供的功能，這將使開發(fā)人員和管理員，以簡化的日常管理及維修他們的 Web 應(yīng)用程序。 靈活的可擴展性 是一個良好的因素和公開的制度，任何組件可以很容易地取代自訂的執(zhí)行情況。無論是服務(wù)器控件，頁處理，匯編，或為核心的應(yīng)用服務(wù)，您會發(fā)現(xiàn)，都是很容易定制和更換，以度身訂造的，以您的需求。開發(fā)人員可以堵 塞在自定義代碼的任何地方網(wǎng)頁的生命周期，以進一步自定義 到他們的需要。 服務(wù)器控件可擴展性。 包括改進的支持，控制可擴展
