【正文】 ent 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 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)。s work and living, learning and modes of munication, emerce applications of Health, through the electronic Business for more useful information and necessary modities are generally concerned about the issue, the paper on this preliminary study. 1. ASP Technical Overview ASP full name of Active Server Pages (dynamic pages) is a Microsoft introduced to replace the CGI (Common Gateway Interface Common Gateway Interface) of the new technology. At present, Inter on many Windowsbased platform for most of the Web site of ASP technology to develop. ASP is a serverside script in the operating environment, the adoption of the environment, users can create and run dynamic, interactive Web server applications, greatly facilitate the managers and viewers. Under normal circumstances, the user through the web browser that most of a static (static) the content of the Inter browser when the HTTP protocol to the site server requests for home contents, site server receipt of the request, after the original transmission Has been designed static HTML documents and data for the browser, users see the staff through the server for good content Home. A static site, Home To update the contents of the site must be in the serverside management to update its manual with the HTML document data, realtime worse. With the development of Web applications, the user would like to see on request and dynamically generated Home, for example, respond to the requirements of users query the database to generate statements. In such circumstances, when users fill in the browser on the data submitted in the form of content, to provide an HTTP request, the site received called for the implementation of server applications, the form of input data, the results will be implemented HTML format to send to the browser, users will be able to see realtime data and content. ASP use ActiveX technology based on open design environment, users can create their own definitions and ponents by adding them to their own dynamic pages with almost unlimited expansion of capacity. ASP and mon dynamic in the
