We have a simple client server architecture between our mobile device and our server both written in Java. An extremely simple ServerSocket and Socket implementation. However one problem is that when the client terminates abruptly (without closing the socket properly) the server does not know that it is disconnected. Furthermore, the ser...

We use the example.com often for domain name reference. I wonder if any IP address used as an example IP address to mention in references like tutorial or notes?. I knew the loop back interface 127.0.0.1 can be used but it has been known for local system always. Can example.com IP Address used for this purpose legally? ...
I have a test driver program that launches a separate test server process. The test server process listens on a local port, and after it's ready, the test driver runs a test that accesses the test server. Currently the test driver repeatedly tries to connect to the local port (loop some, sleep some, try again). It's not an optimal solut...
Hi, We are having performance issues on our web app during peak times, which is currently split between one 2003 IIS6 Web Server, and one SQL Server 2005 DB Server. The query times on the DB server look fine (around 30ms), and the CPU is low (under 20%), yet queries can take a long time to execute on the web server (over 1 second). I w...
I want to download an image from the 'net and set it as the users background. This works great over wi-fi, and some 3G networks, but others (T-Mobile UK, for sure) seem to compress the images before sending them. This effect is noticeable when using the browser, too - however, if you long press on an image and save it, when viewing in ...

Hi. How can I set the SOCKS proxy for a URLConnection given by (new URL(url)).openConnection()? Different proxies are needed on a per-connection basis, so please don't suggest setting system properties. ...
I've recently come across .NET's RDM Socket type (SocketType.Rdm) and its features sound very promising, sounding very much like a reliable connectionless protocol. However, I've found no examples of its usage, and little documentation on the protocol itself. First of all, how do I instantiate a socket of this type? Specifying SocketTyp...
I have ZendFramework based application that is using XMLRPC communication to other ZendFramework app. Both are on the same server (for development). That communication is very slow, and I am trying to find out why. After profiling, I got to the point where there is a slowdown within fgets() of ZF Lib XMLRPC reader. While strace-ing Zen...
What would be the best way to continuously send the mouse position to another computer in C#? So far I use a TCP socket for transportation. I get the ToString() of MousePosition, convert it to byte[] and send that byte array. On the receiving side I append the bytes to a StringBuilder, parse it and construct a new point. At least it wor...

And, how can i send this serialized data over sockets, so that it can be successfully received by the corresponding Java client. Actually i want to convert this binary file into byte array so that it can be send over the sockets. Thanks in advance. ...

When calling Socket.Select with lists that are verified to contain only Socket objects, I sometimes receive the error An operation was attempted on something that is not a socket. I can't find a pattern for occurrence. Socket.Select(readList, writeList, null, timeOut > 0 ? timeOut : 0); ...
I need to send objects around a network. I'm going to be using Twisted, and I've just started looking around the documentation for it. As far as I know, the only way python implements sockets is through text. So how would I send an object using strings? Pickle? Or is there something better? Thanks, Alex ...
