The HTTP Request and the ASP Request Object
As mentioned earlier, the ASP Request object allows you to access both the header and body of the HTTP request sent to the web server by the client's browser. The method of retrieving information from the HTTP request is basically the same for an ASP script as it is for a CGI application. The exceptions come not from the actual request mechanics but from how each type of application is loaded into the web server (CGI versus an ISAPI filter), as described in the first two chapters of this book.
Just as with CGI applications, the client browser can send
information to an ASP script in two different manners. First, it can

Each name corresponds to an element in the form. For example, suppose the user entered Horatia and Thompson into the two fields in the last example and clicked on the Submit button. The submission of the preceding form ...
