There should be a method for specifying when the data orginating from the
server stops. I the case you are communicating with Web server (e.g., GET
www.yahoo.com HTTP/1.0), the server terminates connection with an empty line
or specifies the number of bytes that it will be sending sending before
termination.

If there is no way of finding out when the data stream ends, read all the
data that comes in. When the server closes the socket, you will get an
exception.

Instead of using a 'for' loop try using a do-while construct:

try
{
  do
  {
    readLine();
  }while(true);
}
catch(exception)
{
}

This way, you can get all the data.
