The Achievement Of Trade On WWW.SIOC-NET.COM And The Study Of The Security

Since the 1980's, the world information technique develop soon, especially the emer gence and application of the net , which make information technique can seep through ach realm of the social economic quickly , scribes the social formation in information of the world, the information becomes the world's trend which will not change as the person's will .The Electronic Commerce has been a lot of years since it's emergence with the tide of the times. The technique of empoldering an electronic commerce website is also develo -ping steadily .In the forepart, people of the dynamic website use expandend interface pro -vided by WEB , in C/ C++ or Perl etc, for example ,CGI.Recently JSP, ASP, PHP have become the popular main current WEB development technique .They divide the system in -to showing layer, business logic layer and data layer for setting up a complex distributed system and improving the system data throughputas well as the safety.Among them the most outstanding is JSP .The JSP is a kind of dynamic web page technique standard initiated by the company of SUN Microsystems together with many companies .By adding the Java procedure part (Scriptlet) inside with the marking of JSP( tag) into the traditional web page HTML docu -ment(*.htm,*.Html) , we can constitute the web page of JSP(*.Jsp). When reciving the claim of visiting the web page of JSP,the server of WEB first carries out part of the prog -ram among them, then returns the result in the format of HTML to the customer. Proced -ure can then operate database, refresh the direction of the web page and send out EMA -IL etc.,which is the function to establishes the dynamic website for needing.All procedu -res are carried out in the server,only the result is delivered on the network and request the lowest customer's browser.They can achieve no Plugin, no ActiveX, have no the Java Applet, even no the Frame, and they have the simpleness , independence etc.The system construction experienced successively the first of two layer system cons -truction, then three layer system construction and four layer system construction which was put forward recently. In the initial stage ,the WEB was applied primarily by announ- cing the information on the Internet in static page .The customer sends out the HTTP req -uests to server with the browser, the server of WEB receives the HTTP request from the customer and sends the page requested .With this kind of construction, the page on the website is stati cand can't variey dynamicly according to the actual usage circumstance of the customer.The information promoter of the website passes the renewal the web page on the server to provide to customer the latest information.The customer have to hand over li -mitedly with browser with each other and hardly hand over with customer .The emergen- ce of CGI, ASP and PHP, make it possible that developing the dynamic interactive WEB application .The customer sends out to server the HTTP requests with the browser, the ser -ver of WEB receives the customer's claim of HTTP ,then analyses the claim, if the requ- est is a page of static page, then sends out the page directly.If request of is a dynamic pag -e, then it carries out this dynamic page and sends out to the customer.The dynamic page script in procedure can hand over with the database server with each other.The server of Web can renew the page the information according to the claim of the customer, the web -site information promoter can pass the to customer the latest information, without chang -ing the page.The customer can pass these dynamic pageses to input the information in th -e database which strengthened the customer handing over with the server with each other. Currenttly, the application of many Webs needs complex performance and logical process -sing .Adoptting three layer system construction and gathering the birth of data with the performance of the data in dynamic page.This make dynamic page become very huge, and the performance mix with the logic , which brings great difficulties to the Web .Later a kind of new...
