【正文】 ed. But in the case of other systems, where the client software performs additional tasks on behalf of the server or the users, the mediator is needed to perform this work for the web browserbased clients. The typical solution is to use mon gateway interface (CGI) programs. But this method is unsatisfactory for various reasons. With a CGIbased system, all work, normally done by the client, must be emulated by the CGI programs. Therefore it adds more load to the server machine. Another approach of accessing client/server applications from standard WWW browsers was made by Dossick and Kaiser. They suggested a scheme to use a HTTP proxies as a method of connecting an existing client/server system to the web. This HTTP proxy intercepts HTTP requests for data and transforms them into requests for the legacy system using its native protocols. It is possible to use browserspecific tools like Netscape39。對系統(tǒng)中現(xiàn)有客戶和服務(wù)器進(jìn)行修正改造來執(zhí)行HTTP任務(wù)和高級制圖分析。與傳統(tǒng)集中計(jì)算機(jī)環(huán)境相比，在客戶端/服務(wù)器環(huán)境下，用戶共享數(shù)據(jù)、應(yīng)用、處理進(jìn)程都更加容易?？蛻魴C(jī)/服務(wù)器結(jié)構(gòu)的關(guān)系可以說是兩個(gè)進(jìn)程合作運(yùn)行一些任務(wù)。典型的解決辦法是使用通用網(wǎng)關(guān)接口(CGI)程序。不過，使用這種APIs把產(chǎn)生的基于網(wǎng)絡(luò)客戶端軟件的使用限制在了專用平臺以及專用網(wǎng)絡(luò)瀏覽器上。在單機(jī)環(huán)境下，用戶可以擁有獨(dú)立的數(shù)據(jù)存儲。 用戶管理：用戶信息存儲能夠有效處理增加的用戶。ERIS允許通過用戶管理提出的網(wǎng)絡(luò)瀏覽器申請。服務(wù)器擁有CGI和COM兩個(gè)進(jìn)程?？蛻舳顺绦蛲ㄟ^MS Visual C++及Delphi開發(fā)工具進(jìn)行開發(fā)。參考資料 1.
