Composing Client Requests | When an HTML hypertext link is selected (or the user otherwise specifies a URL), the browser collects information about the protocol, the specified domain, the path to the information, the date and time, the operating environment, the browser itself, and other content information. It then composes a request. For example, to display a page of images based on criteria selected by clicking buttons on a form, the client might construct this URL:
HTTP Server Activity | The client/server nature of Web browsers is deceptively simple. To most users, retrieving information on the World Wide Web is a simple procedure: click on a link, and the information appears on the screen. More knowledgeable users have some understanding of the nature of HTML syntax and the client/server nature of the protocols used. This is usually sufficient for the production of simple, page-oriented Web site content. Authors of more complex Web pages have a wide variety of options to automate the collection and presentation of information using HTML. Before building a Web server application, it is useful to understand... more
Responding to Client Requests | When a Web server application finishes with a client request, it constructs a page of HTML code or other MIME content, and passes it back (via the server) to the client for display. The way the response is sent may differ based on the type of program. When a DLL finishes, it passes the HTML page and any response information directly back to the server, which passes them back to the client. Creating a Web server application as a DLL reduces system load and resource use by reducing the number of processes and disk accesses necessary to service an individual... more
Serving Client Requests | The Web server receives a client request and can perform any number of actions, based on its configuration. If the server is configured to recognize the /gallery.dll portion of the request as a program, it passes information about the request to that program. The way information about the request is passed to the program depends on the type of Web server application: If the program is a Common Gateway Interface (CGI) program, the server passes the information contained in the request directly to the CGI program. The server waits while the program executes. When the CGI program exits, it passes... more
Types of Web Server Applications | Whether you use Web Broker or WebSnap, you can create five standard types of Web server applications. In addition, you can create a Web Application Debugger executable, which integrates the Web server into your application so that you can debug your application logic. The Web Application Debugger executable is intended only for debugging. When you deploy your application, you should migrate to one of the other five types.
