I am developing a server which detects a device and its connection speed . is there any way i can detect a client's connection speed through response headers ??
public class Server_X {
static int count = 0;
public static void main(String args[]) {
Socket s = null;
ServerSocket ss2 = null;
System.out.println("Server Listening......");
try {
ss2 = new ServerSocket(4445); // can also use static final PORT_NUM , when defined
} catch (IOException e) {
e.printStackTrace();
System.out.println("Server error");
}
while (true) {
try {
s = ss2.accept();
System.out.println("connection Established");
ServerThread st = new ServerThread(s);
count++;
System.out.println("total connections :" + count);
st.start();
} catch (Exception e) {
e.printStackTrace();
System.out.println("Connection Error");
}
}
}
}
class ServerThread extends Thread {
static String uagent, uaccept;
static String[] b;
static String[] c;
Server_X obj = new Server_X();
String line = null;
BufferedReader is = null;
PrintWriter os = null;
Socket s = null;
public ServerThread(Socket s) {
this.s = s;
}
public void run() {
try {
is = new BufferedReader(new InputStreamReader(s.getInputStream()));
os = new PrintWriter(s.getOutputStream());
} catch (IOException e) {
System.out.println("IO error in server thread");
}
try {
line = is.readLine();
while (line.compareTo("QUIT") != 0) {
os.println(line);
os.flush();
// System.out.println(line);
line = is.readLine();
b = line.split(":");
if (b[0].equals("User-Agent")) {
uagent = b[1];
// System.out.println(uagent);
}
c = line.split(":");
if (c[0].equals("Accept")) {
uaccept = c[1];
// System.out.println(uaccept);
}
UAgentInfo detect = new UAgentInfo(uagent, uaccept);
}
} catch (IOException e) {
line = this.getName(); //reused String line for getting thread name
//System.out.println("IO Error/ Client "+line+" terminated abruptly");
} catch (NullPointerException e) {
line = this.getName(); //reused String line for getting thread name
//System.out.println("Client "+line+" Closed");
} finally {
try {
System.out.println("Connection Closing..");
if (is != null) {
is.close();
//System.out.println(" Socket Input Stream Closed");
}
if (os != null) {
os.close();
// System.out.println("Socket Out Closed");
}
if (s != null) {
s.close();
//System.out.println("Socket Closed");
obj.count--;
System.out.println("Toatal connections (after closing):" + obj.count);
}
} catch (IOException ie) {
// System.out.println("Socket Close Error");
}
}//end finally
}
}
