Novell Netware Web Server

11. ASP Technology
Active Server Page (ASP) is an open environment where one can combine HTML, scripts and reusable components to create dynamic and powerful web-based business solutions
ASP runs as service of web server and is optimised for multiple threads & multiple users

12. 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 the server, you need only save the changes to the file – the next time web page is loaded, the script will automatically be compiled

13. ASP Built-in Objects Request Response Server
To get information from the user
Response
To send information to the user
Server
To control the IIS

14. ASP Built-in Objects Session Application
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

15. 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

16. Dynamic HTML HTML provides limited interactivity to web pages
DHTML extends HTML with an object model allowing scripting of the objects to change the styles and attributes of page elements
Allows developers to bring more creativity and control to web pages, thereby adding dynamic behaviour

17. Examples of DHTML Use Business Applications Interactive Documents
DHTML can help build dynamic forms (e.g. master detail order entry forms) and can respond to user input, recalculate on the fly and obtain additional information in the background
Interactive Documents
Documents delivered over the internet are essentially confined to page-by-page metaphor, whereas DHTML creates interactive documents that responds instantly to user actions

18. Examples of DHTML Use Dynamic Expansion Table Manipulation
With DHTML Search Result pages can be programmed using scripts to provide a detailed listing 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

19. IIS Application
An IIS (Internet Information Server) application is a Visual Basic application that lives on a Web server and responds to requests from the browser
An IIS application uses HTML to present its user interface and uses compiled Visual Basic code to process requests and respond to events in the browser

20. 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 made up of a special type of object called a webclass, that in turn contains a series of resources called webitems

21. IIS Application
The webclass acts as the central functional unit of the application, processing data from the browser and sending information to the users
A series of procedures are defined that determine how the webclass responds to these requests
The webitems are the HTML pages and other data the webclass can send to the browser in response to a request

22. IIS Application vs ASP Application
IIS applications bear a superficial resemblance to Active Server Pages applications
Both types of applications present dynamic Web sites and perform their processing on the server rather than the client

23. IIS Application vs ASP Application
However, each has its unique advantages. Active Server Pages are for script developers interested in authoring Web pages, and offer the unique capability of intermingling script with HTML
IIS applications are for Visual Basic developers building Web-based applications, rather than Web pages. IIS applications allow for complicated business processing and easy access from almost any browser or platform

24. 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 object model 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 use the DHTML object model

25. IIS Application vs DHTML Application
Location of processing — IIS applications are designed to perform most of their processing on the Web server, but DHTML applications perform most of their processing on the browser machine. You do not create any Web server components when you create a DHTML application
Dependency — DHTML applications are intended for use on intranets, and are dependent on Internet Explorer 4.0 or later, while IIS applications can be used on the Internet or an intranet. End users of an IIS application do not need a specific operating system or browser

26. 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 and processes the server side scripts, (which are enclosed within delimiters “<%” and “%>). The scripts can assign values to variables or request information from server (interaction with other tiers)

27. Browser-IIS Interaction
The processed page containing only HTML and client-side scripts, if any, is sent to the browser

28. 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 prepared using ASP technology (InterDev6.0) and the actual reports have been developed using IIS Application, thus combining the power of the two technologies

29. Case Study – Web based Reports of RuralSoft
The Reports further interact with data services components residing in Microsoft Transaction Server (MTS) to fetch the data from the database
