What is Asp Server Object
The server object is used to provide several commonly used functions
, such as creating a new object , setting time-out property , and converting text
into HTMLs or URLs.

Asp Server Object – Methods
1)Server.CreateObject()
-allows programmer to make instances of components that are running on the server.
There are lots of server components (for example AdRotator,ContentLinker,Browser
Capabilities) that we will see later.
The general syntax for establishing a reference to component of
the server object is:
<%
Set objName = Server.CreateObject(“ClassName.ComponentName”)%>
Eg.
<Set objConn = Server.CreateObject(“ADODB.Connection”)%>
2)Server.MapPath()
– maps the specific virtual path into corresponding physical directory in the
server.We will see this later in scripting object session.
Eg
<%
Server.MapPath(“/virtualpath”)
‘The result is C:\InetPub\wwwroot\virtualpath
%>
3)
Server.URLEncode() -applies URL Encoding rules ,including escape character,
to a specific string.For example space is transformed into (+).
Eg
<%
Response.Redirect(“login.asp?name=”&Server.URLEncode(Request(“name”))&_
“&Password=”&Server.URLEncode(Request(“password”)))
%>
4
)Server.HTMLEncode() – applies HTML encoding to specific string.For example
wherever we find < or > we need to replace it with < or > respectively.
Eg
<%
str = “<body backgroundcolor=Red text=blue>”
response.write (Server.HTMLEncode(str))
%>
5)Server.Execute(path)
– calls an .asp file and processes it as if it were part of the calling
ASP script. The path parameter may be for either an absolute or a relative path.
If the path is absolute, it must map to an ASP script in the same application
as the calling Asp file.

1)Timeout()
– maximum length of time in seconds before a script is terminated.
eg
<%
Server.ScriptTimeOut = 100
%>
