questions)
the problem is that after finally connecting to the server when
i just tried to GET the image -i show u inputs that are taken by my
program
enter the server ip address : 10.10.19.222
enter the port at which to connect to the server : 9029
sucessfully connected to the server
enter the url to request(without spaces) :http://10.10.19.222:9029/
home/Mohan/mine/web/images/tech.jpg
reading frm the server......
now after this the output from the server is saved in a file which has
contents like
HTTP/1.1 200 OK^M

You have already specified the IP and the port number in response to
earlier prompts.
Is your program using all of this answer in the GET request? I believe
that would be wrong. Your program should send
GET /home/Mohan/mine/web/images/tech.jpg
not
GET http:/10.10.19.222:9029/home/Mohan/mine/web/images/tech.jpg
You could try to install and run wireshark to see exactly what the
exchanges look like when you use the browser, and compare when you use
your program.

You are using two different programs to do two different things, so
it's not surprising that you are getting different results. First, you
are simply retrieving the contents of a particular URL without any
processing or analysis. Then you are using a browser to retrieve the
contents that that URL leads to, whether or not the contents are
returned by requesting that URL.
Two different processes, two different results.
If you wan the result a browser will get, you have to act like a
browser. It doesn't just retrieve contents, it analyzes and acts on
them.
