问题 I'm aware of Response.IsClientConnected but in my scenario it has a great lag. Code: // sample code for sending a dynamic file in chuncks long bytesSent = 0; while (continueSending) { if (!AskReceiverToContinue()) break; if (!Response.IsClientConnected) break; // Your suggestion goes here... :) try { Response.OutputStream.Write(buffer, 0, buffer.Length); bytesSent += buffer.Length; } Catch { // To my experience, this is more reliable than Response.IsClientConnected continueSending = false; }

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 3 years ago . I was exploring various methods for implementing communication between a home made TCP/IP server and a Android client application. Some ideas: - TCP/IP Server bases on JSON - Service with WCF library - Some sort of REST server What is the beast strategy and libraries to approach

Stopping a parallel java task with ant

我只是一个虾纸丫 提交于 2019-12-21 04:00:16
问题 I am developing two java programs that run in separate VM's that have a typical server/client relationship. Using ant's parallel/sequential tasks I've been able to get ant to run the server and then the client. I would now like it so that when the client process has stopped, ant kills the server. I've seen this done with custom ant tasks for specific server applications (like TomCat), does any method exist for doing this with generic java processes? 回答1: Since you are developing the server

Python socket server/client programming

孤者浪人 提交于 2019-12-21 03:49:42
问题 So I am just getting into python and trying out some stuff. To start, I am making a server that does simple stuff like "GET"s stored text, "STORE"s new text over the old stored text, and "TRANSLATE"s lowercase text into uppercase. But I have a few questions. Here is my code so far: import socket HOST = '' # Symbolic name meaning the local host PORT = 24069 # Arbitrary non-privileged port s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) print 'Socket created' try: s.bind((HOST, PORT))

Python sockets - keep socket alive?

余生长醉 提交于 2019-12-20 14:37:26
问题 I'm having a little trouble with sockets in Python. Whenever someone connects it works fine but if they disconnect the server program closes. I want the server program to remain open after the client closes. I'm using a while True loop to keep the connection alive but once the client closes the connection the server closes it's connection. Here is the client: import socket, sys conn = socket.socket(socket.AF_INET, socket.SOCK_STREAM) host = sys.argv[1] port = int(sys.argv[2]) conn.connect(

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 years ago .

Advices on server implementation for server/client structure iOS App development?

本秂侑毒 提交于 2019-12-20 08:30:25
问题 There are must be a lot of apps that are designed to communicate with server. My question is only about App installed on iOS device + Server side service interaction. Web app is not what I am talking about, and there should be no webpage involved in this discussion at all. Typical examples are Apps like Instagram and Twitter, in which most of the information exchanged between the App and the server is just data like String, Image and Integers(wrapped in JSON or XML), no webpage presentation

问题 I've being working on a java project using Derbyclient (database locally hosted). I'm done with everything except that when I'm trying the desktop app while I'm not manually connected to the database (from Netbeans), the error in the title pops up and I can't seem to solve it. Thank you for taking the time to read this and help me. 回答1: Derby can be run in two modes embedded or server-based. Server-based allows multiple programs to access the same database. Embedded allows your application to

问题 Hi i have a udp client server code that is not working i ask a general question "Is shane a good kid"both codes have no errors that come up but when i run the code it outputs DatagramPacket sendPacket = new DatagramPacket(sendData, sendData.length, IPAddress, 9876); instead of letting the client greet the server. The flow should be Server initializes and waits for client--client greets server -- server asks the question -- client responds to question-- server tallies the yes no votes and
