IIS 4.0 Installation Installed as a component of WinNT4.0

Run the set up wizard to install web services

and various other components Simply check the items to be installed



IIS 4.0 Management IIS 4.0 introduces Microsoft Management

Console (MMC) a window based tool that

enables the management of all the webservices & applications from a single window



Web Content Creation Tools Hypertext Text Markup Language (HTML),

Dynamic HTML

IIS Application (VB6.0 Feature)

HTML Editors



Content Publishing Environment Web Servers

Microsoft Internet Information Server 4.0 Netscape Communication Server for WinNT

Netscape Communication Server for Unix

Novell Netware Web Server



ASP Technology Active Server Page (ASP) is an open

environment where one can combine HTML,

scripts and reusable components to createdynamic and powerful web-based businesssolutions

ASP runs as service of web server and isoptimised for multiple threads & multipleusers



ASP File File created with Active server Pages have the

extension .ASP

ASP file is simply a file that contains HTML,scripts & calls to components

When a change is made in the ASP file on theserver, you need only save the changes tothe file – the next time web page is loaded,the script will automatically be compiled



ASP Built-in Objects Request

To get information from the user

Response To send information to the user

Server

To control the IIS



ASP Built-in Objects Session

To store information about the user’s current web-

server session

Application

To share application-level information & control

settings for the life-time of the application



Examples of ASP Applications A web-based Personnel Information System

(Leave Monitoring System, HBA Monitoring

System and other modules which form part of employee’s career cycle)

Integrated on-line store, inventory and order-processing system



Examples of DHTML Use Business Applications

DHTML can help build dynamic forms (e.g. master

detail order entry forms) and can respond to userinput, recalculate on the fly and obtain additionalinformation in the background

Interactive Documents

Documents delivered over the internet areessentially confined to page-by-page metaphor,whereas DHTML creates interactive documentsthat responds instantly to user actions



Examples of DHTML Use Dynamic Expansion

With DHTML Search Result pages can be

programmed using scripts to provide a detailedlisting as the mouse passes over it thereby,eliminating redundant fetches from the server

Table Manipulation

Tabular data such as Price lists can be sorted,filtered & viewed using local database engine



IIS Application An IIS (Internet Information Server)

application is a Visual Basic application that

lives on a Web server and responds torequests from the browser

An IIS application uses HTML to present itsuser interface and uses compiled Visual Basiccode to process requests and respond toevents in the browser



IIS Application To the user, an IIS application appears to be

made up of a series of HTML pages

To the developer, an IIS application is madeup of a special type of object called awebclass , that in turn contains a series of resources called webitems



IIS Application The webclass acts as the central functional

unit of the application, processing data fromthe browser and sending information to theusers

A series of procedures are defined thatdetermine how the webclass responds tothese requests

The webitems are the HTML pages and otherdata the webclass can send to the browser inresponse to a request



IIS Application vs ASP Application IIS applications bear a superficial

resemblance to Active Server Pages

applications

Both types of applications present dynamicWeb sites and perform their processing onthe server rather than the client



IIS Application vs ASP Application However, each has its unique advantages. Active

Server Pages are for script developers interested inauthoring Web pages, and offer the unique capability

of intermingling script with HTML

IIS applications are for Visual Basic developersbuilding Web-based applications, rather than Web

pages. IIS applications allow for complicatedbusiness processing and easy access from almost anybrowser or platform



IIS Application vs DHTML Application Like IIS applications, DHTML applications also allow

you to respond to events in an HTML page. However,there are several key differences between the two

types of applications:

Object model — DHTML applications use a different objectmodel than IIS applications to access and work with the

elements on an HTML page. While IIS applications use the Active Server Pages object model, DHTML applications usethe DHTML object model



IIS Application vs DHTML Application Location of processing — IIS applications are designed to

perform most of their processing on the Web server, butDHTML applications perform most of their processing on thebrowser machine. You do not create any Web server

components when you create a DHTML application

Dependency — DHTML applications are intended for use onintranets, and are dependent on Internet Explorer 4.0 orlater, while IIS applications can be used on the Internet or

an intranet. End users of an IIS application do not need aspecific operating system or browser



Browser-IIS Interaction Browser sends an HTTP request to the IIS for

a page on the web server

The web server gets the requested page andprocesses the server side scripts, (which areenclosed within delimiters ―<%‖ and ―%>).The scripts can assign values to variables orrequest information from server (interactionwith other tiers)



Browser-IIS Interaction The processed page containing only

HTML and client-side scripts, if any, is

sent to the browser



Case Study – Web based Reports of

RuralSoft RuralSoft Reports are a combination of IIS

Application and ASP based web pages

The web-site to host the Reports is preparedusing ASP technology (InterDev6.0) and theactual reports have been developed using IIS

Application, thus combining the power of thetwo technologies
