【正文】 ing a URL, the browser does what it would normally do. Otherwise, it calls a custom module to locally parse the content of the ASP file. Furthermore, the browser is involved when the ASP page that will be emulated contains forms and hyperlinks. (I39。ll finish up the code, covering Request and Server plus some other related topics. This month39。s available with IIS . Until IIS , all resources with a .asp extension were subject to parsing, whether or not they contained script code. With IIS this drawback has been eliminated as IIS checks for %...% blocks before loading the ASP parser. An ASPtoHTML converter would also be handy when you need to view ASP pages offline. For example, a client recently asked me about the possibility of using a single development environment for building both Web sites and CDs. I first considered using static HTML pages that could be viewed over the Web or in a local browser, but the idea was soon dismissed given the plexity and the amount of content involved. Also, my client could not guarantee any particular software configuration on the user39。A column. Suppose you have several pages that require some interaction with a database on a frequently visited Web site. Writing them as ASP pages looks like the perfect solution. However, if the database is not very volatile and the page output is not highly dependent on the user39。s input, you could easily resort to plain old HTML for better performance. For example, a list of suppliers is probably the kind of data that you would update only a few times a year. Why rebuild that list on the fly each time it39。s machine, and the only product that could be supplied with the CDs was Microsoft Inter Explorer or a custom Web browser. ASP looked like the natural choice for the Web side of the project, but what about the CD? To make ASP work offline without a Web server, you need code that extracts all the %161。s code shows the potential of this approach and works with typical ASP pages, though it is not prehensive. I won39。ll discuss this further next month.) Given these requirements, to deal with ASP pages offline you need a customized version of the browser. While subclassing Inter Explorer or Netscape Communicator is always possible, I suggest you write a brand new browser from scratch using existing Web browser technology such as the Microsoft WebBrowser control. While I39。ve clicked the Go button, the browser detects whether you39。170。t mean that you cannot use a unified, yet ASPbased approach for the concurrent development of products that deliver content through different media (like the Web and CDs). Offline pages consumed without the intervention of the Web server are normally much simpler and don39。a downloadable ponent (see or use the raw Windows script COM interfaces.

Behind each name (such as MsgBox) there39。s a very mon technique in scripting. Incidentally, this is the same technique that allows IIS to inject the true ASP object model in the scripting context of a serverside ASP page. This workaround also makes it possible for Windows script Host (WSH) scripts to rely on a systemprovided Wscript object. Call in Action When the browser39。re used to on the server.

In fact, the ASP Response object doesn39。170。t be too concerned. Try viewing the same document through Inter Explorer and HTTP and you39。s use the clientside parser to work with a more plex ASP page that involves databases. Figure 8 shows an ASP page that fills and displays a table with a few records taken from an OLE DB data source. Despite the use of ActiveX Data Objects (ADO), the structure of the page is relatively simple. To make this example more realistic I would need to implement the Request object and the simulation of the POST and the GET HTTP mands. I39。t mean that the browser knows how to handle it.
