Active Server Pages have enhanced feature and easier to develop applications. Microsoft Script Debugger. You can use a script debugger debug .asp file. A transactional script. Objects used in ASP pages and pages can run under the transaction environment. Only two results on the page: submit or terminate. The transaction can protect the application from data loss due to failure. Management tool. Many application settings can be performed on the Internet Service Manager, which is the management tool for Internet Information Server and Personal Web Server. Isolation ASP application. You can isolate the ASP application so that they can run within a separate memory space on the web server. When an application fails, you can protect other applications and web servers. It also allows you to stop an application or uninstall its components from memory without stopping a web server. The file is uploaded. The browser can upload the file to the web server through the Posting Acceptor application. You can write an ASP script to send email with information from Posting Acceptor, such as the location and name of each upload file. See the Posting Accepter document (in the catalog table of Microsoft Site Server Express). New ASP components. The ASP provides a new foundation component. Changes to the root directory of the application. The root of the ASP application can be a physical directory on your Web site. Previously, the root directory must be mapped to the virtual directory. You can now indicate the root directory of the ASP application with the Internet Service Manager. The .asp file must be placed in the application tree, the web server can detect changes in the file and automatically reload them. Support Internet Explorer 4.0 channels and Web predictions. When the ASP is to send a file containing the channel definition command, it will automatically tell Internet Explorer 4.0. Using ASP is easy to generate a channel definition (.cdf) file. Support HTTP 1.1 protocol. Internet Information Server and Personal Web Server support HTTP 1.1 protocol. This support can make the ASP's high efficiency of the ASP in response to supporting the HTTP 1.1 browser (such as Internet Explorer 4.0). For example, when returning to the browser, the ASP uses large block conversion encoding to improve network efficiency.
