A7 B7 Printed by the Central Government Bureau of the Ministry of Economic Affairs and printed by a separate consumer cooperative. V. Invention Description (5-1 Field of Invention: The present invention relates to a website generation device, especially to a smart website generation device. 5-2 Invention Background: From the perspective of the user, after the user presses the button where the mouse pointer is located on the Web with a browser, the user can jump from one web page to another. At this time, the way of transmitting information on the Internet, It ’s not all data transmitted at one time, but it is divided into several transactions (trac). The basic principle is to first transfer the location of resources such as text, circles, sounds, and animations on the web page. And the location of resources such as animation. So the browser can quickly send text, and then capture a lot of information such as pictures, sounds and animations. While Hubrowser is crawling this large amount of information, if a website user jumps to another webpage, Carved Browser discards other unobtained data and jumps to the next website. For Web pages, the communication protocol is http (HyperText Transfer Protocol) »If the web server supports other communication protocols, other communication protocols such as ftp and gopher can also be used. Countless web pages that combine several resources (text, pictures, sounds, and animations) on the Web. The way to present them to users is to use a language that describes the distribution of various resources. This is the so-called HyperText Markup Lan.giL 目 ge: HTML . 2 This paper size is applicable to China National Standards (CNS) 8-4 specifications (magic to plus millimeters) Bu-^-Q-pack ------ II ----- Q-rh——Γ .-------- (Please read the notes on the back before filling out this page) 丨 i 丨-5. Description of the invention () A7 B7 Printed by the Shellfish Consumer Cooperative of the Central Standards Bureau of the Ministry of Economy A web page is an HTML file that consists of an HTML file. Once the web page is designed, you can match this HTML file to a host provided by an Internet Service Provider (ISP). The host has a web server running and provides the website designer with a magnetic file. Disk space to place this HTML broadcast. Therefore, HTML is used to describe what is exchanged between the user (C | ient) and the server (server), while http is used to describe the format of the user's request and the server's response format. When the client connects to the web server with a URU (Universal Resource Locator), and when the web server responds, the client sends a request message, usually requesting a web page from the web server, and then the web server Determine the location of the resource and perform the action requested by the client. That is, the resource is passed to the user and the connection is closed to complete a transaction, and the web server continues to wait for the next transaction. However, after the user receives the resource location determined by the web server, because the web page usually contains the addresses of various resources other than text, in order to process them, the user will create more transactions to get the display Information needed for a complete web page. The traditional website generating device is designed by the website designer to use static text in HyperText Markup Language: HTML language to create HTML files. In order to meet the needs of the interactive Web, some extended software types have emerged. After combining HTML with some server-side software, one of the servers such as statistics on the number of users, online voting, and online shopping can be achieved. nnn IK n H0H =-Mn I (Please read the precautions on the back before filling this page)
