Client-side scripting is changing interface behaviors within a specific web page in response to mouse or keyboard actions, or at specified timing events. In this case, the dynamic behavior occurs within the presentation. The Client-side content is generated on the user's local computer system.
Such web pages use presentation technology called rich interfaced pages. Client-side scripting languages like JavaScript or ActionScript, used for Dynamic HTML (DHTML) and Flash technologies respectively, are frequently used to orchestrate media types (sound, animations, changing text, etc.) of the presentation. The scripting also allows use of remote scripting, a technique by which the DHTML page requests additional information from a server, using a hidden frame, XMLHttpRequests, or a Web service.
The first "widespread used" version of JavaScript was in 1996 (with Netscape 3 and ECMAScript standard).
A program running on a web server (server-side scripting) is used to generate the web content on various web pages, manage user sessions, and control workflow. Server responses may be determined by such conditions as data in a posted HTML form, parameters in the URL, the type of browser being used, the passage of time, or a database or server state. Such web pages are often created with the help of server-side languages such as ASP, ColdFusion, Perl, PHP, Ruby, WebDNA and other languages. These server-side languages often use the Common Gateway Interface (CGI) to produce dynamic web pages. Two notable exceptions are ASP.NET, and JSP, which reuse CGI concepts in their APIs but actually dispatch all web requests into a shared virtual machine.
Dynamic web pages are often cached when there are few or no changes expected and the page is anticipated to receive considerable amount of web traffic that would create slow load times for the server if it had to generate the pages on the fly for each request.
Ajax is a web development technique for dynamically interchanging content which sends a request to the server for data. The server returns the requested data which is then formatted by a client side script.
This technique can reduce server load time because the client does not request the entire webpage to be regenerated by the server's language parser; only the content that will change is transmitted. Google Maps is an example of a web application that uses Ajax techniques.
A Web client program (such as a web browser) can access data from many different servers, such as Gopher, FTP, NNTP (Usenet) or HTTP. The HTTP server was designed specifically for the Web, and employs a protocol (system of messages) that supports sending documents from the server to a browser, and that also support sending complex data from the client back to the server. There are several HTTP methods for doing this (in HTTP, method is a technical term for the way in which data are sent between a client browser and server).
All of the client and server components that collectively build dynamic web pages for one website are together called a web application. Web applications manage user interactions, state, security, and performance.
