【正文】 al presentation of the page won’t change, regardless of whether the user requests a fiveday forecast for Denver or Seattle, but accurate weather informationwhich usually gets pulled from a databasedoes. ASPs and JSPs are two of the most popular technologies for generating that type of dynamic content for a Web page. The primary difference between the two development methods is that ASPs generally interact with a backend environment built with Microsoft technologies, while JSPs live in a Javabased environment. Microsoft introduced ASPs, along with its Inter Information Server ,to allow developers to create Web pages that can interact with databases and other applications. An ASP is a serverside scripting environment used to create dynamic, interactive Web pages. It contains HTML, which defines the page layout, fonts and graphic elements, and embedded programming code that’s written in a Microsoft scripting language. Most ASPs are written using Visual Basic Script or JavaScript, but scripting engines for languages such as Perl and Python are available through thirdparty vendors. When a Web browser makes a request, the embedded script runs and pulls up a file with an .asp extension from the Web server, which returns the new results to the browser. 英文翻譯 第 2 頁 As you might expect, Java Server Pages are Sun’s Java equivalent of Microsoft’s ASPs. JSP technology is built on top of servlets, a portable Java program that provides serverside processing. XHTML The days in which you could learn HTML in a short time and craft your own Web page using a text editor are numbered. On the bright side, handling any Web site that’s bigger than 10 or 20 pages is about to get a lot easier. “The big win is that you no longer have to force data structures in HTML.”says Steven Pemberton, chairman of the World Wide Web Consortiums (W3C) HTML Working Group. W3C works with businesses and governments to create Web standards. But browser makers historically haven’t waited for W3C specifications and have either implemented standards before they’re fully defined or implemented them incorrectly. XHTML is the W3Cs attempt to redraw lines blurred by browser makers HTML was created to be a structural languagenothing more. But browser makers quickly began pushing the envelope, adding presentation capabilities. That often involved nonstandard tags or tricky shortcuts such as using tables to lay out a page, which could slow pageloading times drastically and plicate Web site content management. In the XHTML specification, the language is once again only structural. Tags are used to mark up headings, paragraphs, lists, hypertext links and other structural parts of the document. Style sheets, on the other hand, handle issues of presentation: fonts, colors and margins. The intent is to simplify sites, decrease download times and more easily present the same content to multiple types of devices. XHTML works by separating content from style. Content creators craft HTML。 英 文 翻 譯 年 級(jí) :2021 學(xué) 號(hào) :20210051 姓 名 :蘇寧博 專 業(yè) :計(jì)算機(jī)科學(xué)與技術(shù) 指導(dǎo)老師 :陳帆 二零零六年六月 英文翻譯 第 1 頁 Active Server Pages amp。 XHTML amp。 designers create style sheets. This simplifies the Web servers’ job, since site visitors need to download a style sheet only once. Every subsequent page that refers to that style sheet downloads much more quickly. Changing the look of the site is simplified because you have to change only a few style sheets, not thousands of HTML pages. 英文翻譯
