Multi-threaded TCP Connection Request

[BlueChinchillaEatingDorito]

	public static void main(String argv[]) throws Exception {
		
		try {
			// Create listener socket
			ServerSocket serverSocket = new ServerSocket(port);
			while(true){
		    	Socket clientSocket = serverSocket.accept(); 
				HttpRequest request = new HttpRequest(clientSocket);
				Thread thread = new Thread(request);
				thread.start();
			}
		}
		catch (Exception e) {
	    	System.err.println(e.getMessage());
	    }
	}

So I'm doing assignment for my networking course and I need to make a multi-threaded webserver to handle multiple clients and/or requests in parallel. The issue I have is that whenever I try to access this local webserver through my browser, it basically executes the run() function in HttpRequest twice for whatever reason and I can't seem to figure out why. Can anyone shed some light?
