Asp Response object

is used to send server’s output to the client.the Response object is the counterpart of Request

object,ie.In asp Request object collects information from the client and Response object

sends the information to the client by writing to the outgoing page.

Asp Response object Methods

and Properties

Response object – Write method

We have seen that

the primary function of response object is to send information back to the client.Write

methods of Response object is used to send information back to the client.The

syntax is:

Response.write

(information) .

The

information can be contents of server-variables,the return value from a function

, or a sting.

Suppose

we have a block of HTML code and we want to insert a single piece of ASP code

into it we can use shortcut method .The syntax is:

<%=

information%> .This is same as writing <%Response.write(information)%>

Response object – BinaryWrite()

The BinaryWrite method writes the specified information to the current

HTTP output without any character conversion. This method is useful for writing

non-string information such as binary data required by a custom application.The

Syntax is:

Response.BinaryWrite

data

Response object – AppendToLog()

The AppendToLog method adds a string to the end of the Web server

log entry for this request.In order for the specified string to be recorded in

the log file, you must enable the URI Stem option of the Extended Properties property

sheet for the site whose activity you wish to log. The Syntax is:

Response.AppendToLog

string

Response object – Buffer Property

Sometimes

we come across ASP scripts which takes long processing time.In this case we

can send some information to client , to let them know that the script is processing.There

is one property and three methods that will allow us to control the when the

output stream is send to the client.

Buffer

property is used to tell the ASP that we are manually controlling when the HTML

stream is send back to the browser.By default buffering is turned OFF.So first

we should turned it ON by inserting the following statement after language declaration

(if one is used) , but before any HTML written.the syntax is:

Response.Buffer

= true

Response object – Flush method

Flush

method sends any previously buffered output to the client immediately, but continues

processing the script.

This can be useful for displaying partial

results before your script finishes processing so that user does not get impatient

while waiting for the full results.

The syntax is:

<%Response.flush%>

Top


Response object – Clear Method

This method erases

any already buffered HTML.It will erases the information that has been added

to the HTML since the last call to response.Flush.If you have not called response.Flush

, then it will erase all the information that has been added since the beginning

of the page ,except headers.The syntax is:

<%Response.Clear%>

Top


Response object – End Method

This method causes

the server to stop processing the script and send the buffered output.The syntax

is:

<%Response.End%>

Top


Response object – Expires property

This property

specifies the number of minutes before a page cashed on the browser expires.ie,

if the user returns to the same page before the specified number of minutes

the cashed version displayed.The syntax for setting this is:

<%Response.Expires

= minutes%>

Top


Response object – ExpiresAbsolute

Using this property

we can set the date and(or) time at which page cashed on the browser expires.

<%Response.ExpiresAbsolute

= #DateTime#%>

Top


Response object – CacheControl

If you set this

property to Public, proxy servers can cache the output generated by ASP.Setting

CacheControl to public may improve the perceived performance of your .asp files.

The default value is Private. The syntax is:

 

Response.CacheControl

=value

Top


Response object – Redirect method

This method is

used to redirect to another page.The syntax is:

<%Response.Redirect%>

Please

note that calling redirect method after adding any information to HTML stream

will cause an

Error.
