Which network protocol to use for lightweight notification of remote apps?

I have this situation.... Client-initiated SOAP 1.1 communication between one server and let's say, tens of thousands of clients. Clients are external, coming in through our firewall, authenticated by certificate, https, etc.. They can be anywhere, and usually have their own firewalls, NAT routers, etc... They're truely external, not ju...

HTTP request using asynchronous pluggable protocol in Java

I need to make an HTTP request to a resource that looks like "xy:index.html" in Java. The HTTP implementation does not have to be sophisticated. I just need to be able to do this to avoid same-origin violations when running in development mode for a GWT app by forwarding HTTP requests on the server-side to the "xy" protocol. Any clue...

Is there a social networking protocol

Social networking is great, but there is something fundamentally wrong with the way social networking is implemented today in most popular services. I'll put it in this example: Imagine that there is no SMTP, and consequently, it is globally assumed and accepted that you can only send email to addresses on the same domain. The result wou...

AJAX HTTP protocol response problem with custom server

I've started to add HTTP support to a custom C# non-webserver application which seems to work fine from Firefox/IE/Chrome when typing in the URL directly to the browser - where I can see a returned text string in the page from my application. The problem is when I try do the same from a HTTPRequest in JavaScript on a web page I don't ge...

USB HID protocol question

I'm implementing USB on a PIC 18F2550 using a generic HID interface. I've set up the HID profile configuation to have a single 64 byte message for both inputs and outputs. Now it's basically working. The device registers OK with windows. I can find it in my program on the PC and can send and receive data to it. The problem is this thoug...

Communication protocols in UDP

After many hours, I have discovered that the given udp server needs the following steps for a successful communication: 1- Send "Start Message" on a given port 2- Wait to receive from server on any port 3- Then the port dedicated to you to send further data to the server equals the port you have received on it + 1 So I am asking if thi...

How to design a high-level application protocol and data format for metadata syncing between devices and server?

I am looking for guidance on how to best think about designing a high-level application protocol to sync metadata between end-user devices and a server. My goal: the user can interact with the application data on any device, or on the web. The purpose of this protocol is to communicate changes made on one endpoint to other endpoints thr...

Browser plugin which can register its own protocol

I need to implement a browser plugin which can register its own protocol (like someprotocol://someurl) and be able to handle calls to this protocol (like user clicking on 'someprotocol' link calls function inside my plugin). As far as I understand, Skype does something similar, except I need to handle links within page context and not in...

Basically, each command had a certain meaning, eg: 1 = character starts turning right 2 = character starts turning left 3 = character stops turning 4 = character starts moving for...

Talking with Selenium RC directly

I am curious if it's possible to let the Selenium RC server directly issue it's command over a socket connection to the target application without the JavaScript layer in between. If so, what's the best approach to do this? I can't make a client driver because that's the other way around. Anyone having any suggestions? I would love to ...

Linux network stack : adding protocols with an LKM and dev_add_pack

Hello, I have recently been trying to familiarize myself with the Linux Networking stack and device drivers (have both similarly named O'Reilly books) with the eventual goal of offloading UDP. I have already implemented UDP on the NIC but now the hard part... Rather than ask for assistance on this larger goal I was hoping someone coul...

Networking with extremely high latency.

Are there any protocols, systems, etc. experimental or otherwise designed for allowing normal (as normal as can be) network operations (E-mail, DNS, HTML, etc.) over very high latency links? I'm thinking of minutes to an hour, or maybe two. Think light speed lag at a solar system scale. As a side note: research or speculation on the s...

I need an efficient protocol between webservices that are more or less supported by all major languages

Some conditions: I has to be more "efficient" than normal XML which adds a lot of extra data and the tools to read/write is too heavy It h...
