Specific settings: in the Web site of the Directory Security property page, select the Anonymous access and authentication control for editing. Allow anonymous access to client account IUSRComputername to establish a connection with the Web server (to provide a random password). For 遼寧科技大學(xué)本科生畢業(yè)設(shè)計(jì)（論文） 第 4 頁(yè) nonanonymous access, there are three types of authentication: basic authentication, allows the user name and password unencrypted (clear) is sent。 because of its serverside implementation, developers do not have to worry about other people download programs for the theft of programming logic. ASP called by suffix. Asp to achieve the ASP document, a. Asp document equivalent to an executable file, it must be placed on Web servers are enforceable under the authority of the directory. When a user from the browser entered. Asp files after the address, the browser will request the URL to Web Server, if the Web Server tops the ASP, called on the ASP. ASP read out accordingly. Asp paper to explain and enforce an order to generate a dynamic HTML pages to return a Web Server, Web Server and then send the results to the browser. ASP and HTML document similar to the production and the development of integrated and HTML, in the same process can be pleted, the ASP will be able to use the implementation of the scripts embedded in HTML documents (HTML files will be changed to the name suffix. Asp), which makes HTML documents The preparation and development of the script together. ASP through the builtin objects, the server ponent (Server Component) can be pleted very plicated task, but users can also use their own or others to plete the development of the server ponent of specialized tasks. Comparing the gateway server and ASP expansion mode has the following advantages: (1) ASP VBScript used by the scripting language from the VB, easy to learn. (2) directly into the HTML scripting language, do not need to pile and can connect 遼寧科技大學(xué)本科生畢業(yè)設(shè)計(jì)（論文） 第 3 頁(yè) directly to explain operation. (3) the use of ADODB ponents easy access to the database. (4) Objectoriented programming, which can be expanded ActiveX Server ponent functions, in theory, can achieve any function. (5) does not exist browser patibility problems, ASP is in the process of serverside run. (6) can be hidden code, the protection of labor results. serverside security technology (1) Directory file protection 1) NTFS permissions. NTFS file system provides more security than the Fat32 file management, file access control through a table (ACL) defines the user access to files and directorylevel permissions, if the user has permissions to open the file, the puter allows the user to access files . Directories and files by setting access rights, the prohibition has nothing to do users of the directory file copy, modify, delete, etc. operations, restrict the invasion of the system. 2) Virtual directory and its property. Virtual directory hide the directory structure on the site of important information, in the Asp environment, a safer approach is to Asp separate scripts and HTML files stored in different directory, will be stored as HTML files readonly attribute will be stored Asp script directory attribute is set to implement. 3) To prevent the document view Asp. IIS or own document, you can view the source code of Asp procedures in order to steal information. Web server can delete or disable access to the documents stored in the files. (2) Restrict access to technology 1) IP address restrictions. IIS will authorize or reject a specific IP address of their visit, by refusing a visit to a specific IP address in order to exclude interference invasion. The setting: A start ISM (Inter Service Manager)。遼寧科技大學(xué)本科生畢業(yè)設(shè)計(jì)（論文） 第 1 頁(yè) 外文文獻(xiàn)閱讀與翻譯 英文原文 ASP technology in the use of Emerce Based on ASP technology in emerce application of the preliminary study, in connection with reality, given the ASP pages in the design of some of the key tec
