WEB SERVER SOFTWARE FEATURE SETS

Web Server Software Features

• All Web server software provide some basic features

which can be classified as: – Core capabilities

– Site management

– Application Construction, and

– Electronic commerce

UNIT-3 IT2031


Core Capabilities

• Client Request Processing: A Web server processes client

requests that are sent using HTTP protocol, both for static and

dynamic pages

• IP-Sharing or Virtual Server: A Web server can work as many

virtual Web servers, serving many businesses with individual

domain names but all domains directing to the same IP address

of the computer

UNIT-3 IT2031


Core Capabilities (contd..)

• Logical File: A Web server can have a logical file name

corresponding to a physical file

– The physical file may be in the same computer or in another

computer, and also the logical name and the physical name do not

have to be same

– The Web server translates a logical URL into a physical file address

– Example, the physical file “c:\Inetpub\wwwroot\default.htm” may be

configured as logical URL: www.Mybusiness.com/home.htm

UNIT-3 IT2031


Core Capabilities (contd..)• Security: Web servers are located publicly on the Internet or

privately in an organizational intranet, usually behind the firewalls. – The public documents are configured to be viewed by anonymous

users

– For extranet users, the files and folders are configured for validation of username and password. Access controls provide or deny access to files based on the username or by extranet company URL

– Web servers allow processing digital certificates and private/public key pairs.

– Web servers also support Secure Socket Layer (SSL)

UNIT-3 IT2031


Core Capabilities (contd..)• FTP: Web servers provide File Transfer Protocol (FTP)

services. Thus users can transfer files to and from the server.

• Searching: Search engines and indexing programs are standard components of the Web server. – Search engines or search tools search either the existing site or the

entire Web.

• Site Analysis: Web servers can capture visitor information that are stored in a log file. Information includes: – who is visiting the Web site (the visitor’s URL)

– how long the visitor browsed the site

– the date and time of each visit, and the pages visited

UNIT-3 IT2031


Site Management• A Web server provides tools to manage multiple Web sites, file

security, virtual file, and log file analysis

• Administration of a Web server can be performed from a remote

computer in the network

• Administrators can grant or deny Web access to individual

computers, groups of computers, or entire domains

• Administrators can stop and restart all Web services without

stopping and restarting the computer

• Site management also include authoring tools such as Microsoft

Front page 2000

UNIT-3 IT2031


Application Development

• Application development includes Web editors and extensions

to produce Web pages – either static or dynamic. These

include HTML editors such as FrontPage for static Web pages

• For dynamic Web pages, there are protocols such as Common

Gateway Interface (CGI), Application programming Interface

(API), and Active Server Pages (ASP) that are used by

programs such as Java, C++, and VBScriot to develop dynamic

Web pages

UNIT-3 IT2031


Application Development (Contd..)

• Active Server Pages (ASP):

– Developed by Microsoft, it is a server-side scripting technology to

build dynamic Web applications.

– With ASP, one can build Web pages with embedded query strings

for database manipulation using scripting languages such as

VBScript and JavaScript.

UNIT-3 IT2031



• Open Database Connectivity (ODBC) and ActiveX Data Object (ADO) mechanisms, both developed by Microsoft, can be used to develop dynamic Web pages that use database connection of variety of databases from different manufactures (such as SQL Server, DB2, and Oracle)

UNIT-3 IT2031



• Java Database Connectivity (JDBC):

– Similar to ODBC, JDBC is another technology developed by

Sun Microsystems, that is used for Web-database

applications,

– It is written in Java

– It runs on Unix Web servers

UNIT-3 IT2031


Electronic Commerce

• Some Web servers provide advanced services that support online selling and buying (such as shopping cart and catalog services)

• An electronic commerce software can also provide templates and other tools to quickly develop an e-commerce site. This might include templates for product browsing, shopping carts, and credit card

processing.

UNIT-3 IT2031


Electronic Commerce (contd..)

• An electronic commerce software is a separate software that

integrates with an existing Web server.

• Microsoft Commerce Server is an electronic commerce software

that enables businesses to engage customers, transact

business, and analyze commerce Web sites more effectively.
