PROG PROGR RAM NO: - 1 Unit/Topic: Web Server and Browser  Browser 

PROBLEM DEFINITION: Study of web server and web Browser.

OBJECTIVE: To understand understand working working of web server and browser. browser.

THEORY: Web Server: computer on which a web site is hosted and a program that A web serv server er can can mean mean two thing thingss - a computer on runs on such a computer. So the term web server refers to both hardware and software . We'll look at each of these individually. A web site is a collection collection of web pages. And web pages are digital files, typically written using HyperText Markup Language (HTML). For a web site to be available to everyone in the world at all times, it need to be stored or "hosted" on a computer that is connected to the internet. Such a computer is known as a web Server. Hardware:

There are are several requirem requirements ents for a Server Server computer computer - it needs to be fast, fast, have a large storage storage capacity hard disk and lots of RAM. But the most important is having a permanent internet address also known as an I.P. (Internet protocol) address Software:

A web server program is software software that runs on the web site site hosting Server computer. Its Its main  purpose is to serve web pages; which means it waits w aits for requests from web browsers (also known as clients ) and responds by sending the required data back.

Role of Web Serv Server: er:

Web servers servers - the computer computer or the program program - have a vital vital role on the Internet. Internet. The The Server  Server  machine hosts the web site while the server program helps deliver the web pages and their  associated files like images and flash movies. The process of loading a web site/page in a web browser starts with the user either entering the URL in the address bar or clicking on a link. You should know that each web page has a unique address (or URL) on the internet; which means the same page cannot exist in two places.

The browser now needs to send out a request for the web page. Behind the scenes, the URL of  resolved into an I.P. address , which in English means, converted to the requested web page is resolved an I.P. addresses - something that computers computers understand. The I.P. address points to to the location of the web site host and the t he request is forwarded to Server computer and passed on to the server  s erver  software. The server software now takes up and hunts for the requested web page on the hard disk. On finding the file, it sends back a response and the web page file to the browser which then starts displaying the page. A typical web page not only has text but also embedded multimedia elements like images and Flash animation. These "extra" files are separate from the actual web  page and need to be sent one by one for the browser to display the web page correctly. ONLY the web browser determines how a web page is displayed; the web server has h as no control over  this. The job of a web server ends once it processes the request from a browser and sends the required information.

Web Browser: A Web browser is a software software application application for retrieving, retrieving, presenting, presenting, and traversing traversing information information resources resources on the World Wide Wide Web. An information resource is identified identified by a Uniform Uniform Resource Resource Identifie Identifierr (URI) and and may be a web page, image, image, video, video, or other other piece piece of content. content. Hyperlinks Hyperlinks  present in resources enable users to easily navigate their browsers to related resources.

Web Browser Features: ActiveX: ActiveX is a technology used by Microsoft Microsoft Internet Explorer on Microsoft Windows systems. ActiveX allows applications or parts of applications to be utilized by the web browser. A web page can use us e ActiveX components that may already reside on a Windows system, or a site may provide the component as a downloadable object. This gives extra functionality functionality to traditional web browsing, but may also introduce more severe vulnerabilities if not properly implemented.

browser. Netscape has developed Plug-ins: Plug-ins are applications intended for use in the web browser. the NPAPI standard for developing plug-ins, but this standard is used by multiple web browsers, including Mozilla Firefox and Safari. Plug-ins are similar to ActiveX controls but cannot be executed outside of a web browser. Adobe Flash is an example of an application that is available as a plug-in. your system to store data for specific web sites.

Cookies may contain information about the sites you visited, or may even contain credentials credentials for accessing the site. Cookies are designed to be readable only by the web site that created the cookie. Session cookies

are cleared when the browser is closed, and persistent cookies will remain on the computer until the specified expiration date is reached. JavaScript is a scripting scripting language language that is used to make web sites more interact interactive. ive.

JavaScript JavaScript gives HTML designers designers a programming programming tool tool - HTML authors are normally not programmers, but JavaScript is a scripting language with a very simple syntax! Almost anyone can put small "snippets" of o f code into their HTML pages JavaScript JavaScript can put dynamic dynamic text into an an HTML page - A JavaScript statement like this: document.write("" + name + "") can write a v ariable text into an HTML  page JavaScript JavaScript can react to to events events - A JavaScript can be set to execute when something happens, like when a page has finished loading loading or when a user clicks on an HTML element JavaScript JavaScript can read and and write HTML elements elements - A JavaScript can read and change the content of an HTML element JavaScript JavaScript can be used to validate validate data data - A JavaScript can be used to validate form data before it is submitted to a server. This saves the server s erver from extra processing JavaScript can be used to detect the visitor's browser - A JavaScript JavaScript can be used used to detect the visitor visitor's 's browser browser,, and - depending depending on the browser browser - load another another page specifically specifically designed designed for that browser  browser  JavaScript can be used to create cookies - A JavaScript JavaScript can be used to store store and retrieve information on the visitor's computer  Interpreted language -JavaScript is an interpreted language (means that scripts ex ecute without preliminary compilation)

To insert a JavaScript into an HTML page, we use the tag. Inside the tag we use the type attribute to define the scripting language.So, the and tells where the JavaScript starts and ends: ….

JavaScript Functions

To keep the browser from executing ex ecuting a script when the page loads, you can put your script into a function. A function contains code that will be executed by an event or by a call to the function. You may call a function from anywhere within a page (or even from other pages if the function is embedded in an external .js file). Functions can be defined both in the and in the section of a document. However, to assure that a function is read/loaded b y the browser before it is called, it could be wise to put functions in the section. function displaymessage() { alert("Hello World!"); }

Events By using JavaScript, we have the ability to create dynamic web pages. Events are actions that can be detected by JavaScript. Every element on a web page has certain events which can trigger  a JavaScript. For example, we can use the onClick event of a button element to indicate that a function will run when a user clicks on the button. We define the events in the HTML tags The tag supports the following event attributes: Attribute onclick ondblclick onmo onmouse usedo down wn onmo onmous usem emov ovee onmo onmous useo eout ut onmo onmous useo eove verr onmouseu seup onkeydown onkeypr eypreess onkeyup onreset onsubmit

JavaScript Form Validation

JavaScript can be used to validate data in HTML forms before sending off the content to a server. Form data that typically are checked b y a JavaScript could be:    

has the user left required fields empty? has the user entered a valid e-mail address? has the user entered a valid date? has the user entered text in a numeric field?

Browser Detection

Almost everything in this tutorial works on all J avaScript-enabled browsers. However, there are some things things that just don't work work on certain browsers browsers - especially especially on older browsers. browsers. So, sometimes it can be very useful to detect the visitor's browser, and then serve up the appropriate information. The best way to do this is to make your web web pages smart enough to look one way to some  browsers and another way to other browsers. Th e Navigator object contains information about the visitor's browser name, version, and more.The Navigator object contains all information about the visitor's browser. We are going to look at two properties of the Navigator object:  

appName appName - holds the name name of the browser  appVersion appVersion - holds, among among other things, things, the the version of the browser  browser 

var browser=navigator.appName; var b_version=navigator.appVersion; var version=parseFloat(b_version); document.write("Browser name: "+ browser); document.write(""); document.write("Browser version: "+ version);
