3. Agenda
1. Discussing on Architecture of Web
1. What is ASP and Digging in the
development framework with ASP
3. Classic ASP at a glance
4. ASP Object and Components

4. Architecture of web

5. Difference between Browser and Server
Server
1. Software to serve documents on web.
2. Receive HTTP request and sends appropriate
HTTP response
3. Have area to store website documents
4. Eg Apache Server, Internet Information Server,
Heroku,AWS
Browser
1. Software to surf web pages and content
2. Sends a HTTP request and receives and
HTTP response
3. Store data in cookies in local machine
4. Eg. Google Chrome , Firefox

6. Static Pages
Designed with HTML , JS , CSS
etc
Executed on browser
Data do not change with time
Are simple and takes less time to
load
Usually no involvement of
Database

7. Dynamic Pages
Designed using Node.js , PHP ,
Python , ASP , ASP.NET
Partially or fully executed on
Server.
Data may change with time and
action.
Require more time to load due
the server execution and
database calls

8. Client Server Architecture of Web
Two tier architecture
Client Server is one of many architecture
for web.It creates most of the web we
see around us.
Client send the Request.
Server send the response back.

9. Three-tier Architecture of Web
Model some form of application logic
between client and server.Usually by
scripting language like JS.
Action on the client side is influenced by
scripts so that no asynchronous data transfer
is necessary.
On the server side, modified content is stored
via the application server on the database
server.

11. Simple Web Page
A simple HTML page may
contain three elements
1. HTML tags : to create the
structure of the web page
2. CSS code : to give styling
to the created structure
3. Scripting code : to give
interactivity to the
produced web page
index.html

12. ASP and Various Development
Framework

13. ASP
Active Server Pages
Program that runs inside IIS (Internet
Information Service) server
Used to create dynamic and interactive pages
Microsoft’s initiative to create dynamic web
pages
Internet Information Services Server
Windows Server-based web application used to
deliver website content over the internet to an
end user.
Bundled with all Microsoft windows Server
Products

14. Working of ASP code

16. A Glance At Classic ASP

17. Classic ASP
A ASP page contain
1) HTML Tags - ASP can be regarded as
extension of a simple HTML file
2) Scripting Language - use to perform
operation on both client and server side .
Javascript and VBscript are available scripting
language here.
3) ASP Built-in Objects - encapsulation of
methods and user variable. Can have properties,
method, event, collections.
4) ASP Components - built in module to handle
some necessary tasks like database access, file
creation and exploration etc

18. Syntax for Classic ASP
Normally a HTML file with scripting in between.
Code to be executed in server side is written
between <% %>
Response.Write is a basic function to write
content on html document
Two type of Scripting language used
1. Client Side Scripting - runs on browser -
(by default Javascript)
2. Server Side Scripting - runs on server -
(by default VBscript)
Scripts in ASP files are executed on server.

19. Simple ASP code
ASP files are identified by .asp
extension
The example contain the code where
only line between <% %> will be
processed in server side
OUTPUT of the file will be the result
text: “My First Webpage”
server.asp

20. Scripting in ASP
Example to two type of scripting is
given
Client side scripting do not require any
parameter . We can give language as
prefered (by default Javascript)
Server Side Scripting require extra
parameter of runat which has two
values “client” and “server”
Client Side Scripting
Server Side Scripting

21. ASP Variable
Variables are "containers" for
storing information.
We declare variable with Dim
(dimension) keyword
No data type need to be explicitly
define, declared as variant type
Can use Option Explicit to restricting
yourself in declaring variable only once

22. ASP Array
An array variable is used to store
multiple values in a single variable.
Dim name(n) defines a array with size
of n and index starts from 0 to n-1
Dim table(n,m) defines a two-
dimensional array
Multi-dimensional array of upto 60
dimensions can be defined in VbScript

23. ASP Include
You can insert the content of one
ASP file into another ASP file
before the server executes it, with
the #include directive.
Can use .inc (include) and .asp
extension for including file
Can use keyword virtual and file to
define the path of the file
Note : Directives are preprocessed in
the server

24. ASP Objects and Components

25. ASP Objects
Objects are a way of encapsulating multiple
methods (they're like functions) and variables in
one easy to manage user-variable (called
objects)
Objects in ASP resemble other Object Oriented
Programming languages
An ASP Object can contain -
Collection , Properties , Methods , Events
Objects were created to combat the increasing
complexity of programming.
It makes programming easier and your code
more human readable.
Object in ASP is created by passing a name string to the
Server.CreateObject function

26. ASP Built-in Objects
Collection of predefined object explicitly provided to
user by IIS servers
An ASP Built-in Object can contain -
1. Collection- set of data to define the state of
object.
2. Properties - set of variables to modify the data
3. Methods - set of function to operate on
predefined entities
4. Events : special function that operate on
triggering of certain event
Some built-in objects are
1. Request Object : object that have HTTP
response of client
2. Response Object : object that have HTTP
response of server
3. Server Object : object that contain
environment variable of server
4. Session Object : object that contain
session control information

27. Request Object
Collections:
1. QueryString: allows to retrieve value for
get request.
2. Form : allows to retrieve value from post
request.
3. Cookies: allows to retrieve value stored as
cookies
4. ServerVariable : contain value of
predefined environment variable
Retrieves the values that the client browser passes
to the web server during an HTTP request.
Can access data from both header and body.
Use to issue server side processing like form
submission
Properties :
1. TotalBytes: read-only property to specify no.
of bytes sent by client in HTTP request

28. Request.QueryString
The Request.QueryString
command is used to collect values
in a form with method="get".
Information sent from a form with
the GET method is visible to
everyone in address bar and has a
limit on size
Eg.https://www.ourdomain.com?s
erver.asp?name=Jhonny&pno=965
6566969
client.html
server.asp

29. Request.Form
The Request.Form command is
used to collect values in a form
with method="post".
Information sent with the
method=”POST” is invisible to
others and has no limits on the
amount of information to send.
Eg.https://www.ourwebsite.com/
server.asp
client.html
server.asp

30. Response Object
Collection:
1. Cookie :Sets a cookie value. If the cookie
does not exist, it will be created, and take
the value that is specified
The Cookies collection is used to set or get
cookie values. If the cookie does not exist, it will
be created, and take the value that is specified.
The Response object is used to send output to
the client from the web server.
ASP Properties need to be inserted after
<%@ LANGUAGE="VBSCRIPT"%> directive, but
before the first HTML tag.
Gives potent control over what you send to
client over the web

31. Response Object
Methods :
1. AddHeader : add a HTTP header and
value to the response.
2. AppendToLog: add specific string at the
end of server log
3. Redirect : redirect the user to different
URL
4. End : stops processing a script and return
current result
Properties:
1. ContentType :sets the HTTP content
type for response object
2. Expires : sets how long the page will be
cached in browser
3. IsClientConnected : specifies whether
client is still connected to server or not
4. Status : specifies the status send by
server

32. Response.Cookies
Syntax:
Response.Cookies(name)= value
variablename= Request.Cookies(name)
Note: The Response.Cookies command
must appear before the <html> tag.
Setting Cookies
Getting Cookies

33. Response.AddHeader
Syntax:
response.AddHeader name,value
Once a header has been added, it
cannot be removed.
Have two parameters
1. Name : name of new header
2. Value : initial value of header
Setting Cookies
Checking Response Header

34. Response.ContentType
Syntax
response.ContentType[=contenttype]
Parameter
1. Contenttype :A string describing the
content type.
Some Common content types are :
<%response.ContentType="text/HTML"%>
<%response.ContentType="image/GIF"%>
<%response.ContentType="image/JPEG"%>
<%response.ContentType="text/plain"%>
Setting Content Type

35. Server Object
Methods :
1. CreateObject -Creates an instance of an
object
2. Execute -Executes an ASP file from inside
another ASP file
3. Transfer - Sends (transfers) all the
information created in one ASP file to a
second ASP file
4. URLEncode : Applies URL encoding rules to a
specified string
The Server object is designed to help you carry
out various tasks on the server.
It is used to access properties and methods on
the server.
Properties:
1. ScriptTimeout - Sets or returns the
maximum number of seconds a script can
run before it is terminated

36. Server.CreateObject
The CreateObject method creates an instance
of an object.
Syntax:
Server.CreateObject(progID)
progID : The type of object to create
Creating Object
Destroying Object

37. Session Object
A Session object stores information about, or
change settings for a user session.
Collections:
1. Contents :Contains all the items
appended to the session through a script
command
2. StaticObjects : Contains all the objects
appended to the session with the HTML
<object> tag
Methods:
1. Abandon : Destroys a user session
2. Contents.Remove: Deletes an item from
the Contents collection
3. Contents.RemoveAll:Deletes all items
from the Contents collection

38. Session Object
Properties :
1. SessionID : returns a unique id for each
user generated at server
2. Timeout : set timeout period for session
3. LCID : return location integer according to
which date , time other content can be set
Events:
1. Session_OnEnd : occurs when session
end
2. Session_OnStart : occurs when session
start.

39. Session Event
Session Events are the special type of
subroutines that are fired when a specific
event takes place.
ASP provide two basic events that can be as
1. Session_OnStart :
Fired when the server is first calls from
client session.
1. Session_OnEnd:
Fired when the server closes the client
session

41. ASP Components
Collection of code that has been made by
Microsoft and included in IIS. With the use of
ASP you can unlock the power of this pre-made
code.
These objects can be used to do a ton of things,
such as: an easy-to-use ad rotation service, an
interface to a database, a means of
manipulating files and much more.
Making use of Microsoft's ASP Components in
your ASP programming will allow you to do so much
with ASP that you'll be kicking yourself for not using
components earlier. You can access these built in
components by creating objects of them. See our
previous lesson if you need a refresher on what ASP
Objects are.

42. File System Access
The FileSystemObject object is used to
access the file system on a server.
This object can manipulate files, folders,
and directory paths. It is also possible to
retrieve file system information with this
object.
