Whenever a user requests a page from a Netscape Enterprise Server, a request object is created to manage storage, methods and properties for that request. When the request is returned, the object can be destroyed as it will have no further use.
The request object contains details of the URL, form data and search criteria. This is the way that you access the data in a form submit for example.
There are other properties belonging to this object that can tell you a lot about the client and what is happening there.
The ASP server also supports a Request object, whose name is capitalized. It's there for the same purpose and manages the incoming requests from the the clients' browsers.
The Request object supported by ASP is quite different to that supported by NES. Since the tag introducer is quite different for each server-side system, it is unlikely you'll deploy common scripts across NES and ASP running on IIS.
