In this series I will detail what I found out empirically about how mochiweb performs with lots of open connections, and show how to build a comet application using mochiweb, where each mochiweb connection is registered with a router which dispatches messages to various users.
with details how to tweak the kernel and make a flood test
Exemple d'utilisation de Comet avec Tomcat 6.
A Twisted-based publish/subscribe messaging server that uses the STOMP protocol
A recent set of HTML5 discussions are changing the course of Comet
Comet doesn’t have to be a hack. Currently, as we saw last time, Comet relies on undocumented loopholes and workarounds, each one with some drawbacks. We can make Comet work effectively in every browser, using streaming transports on subdomains of the same second-level domain, or using script tag long polling across domains. But this leaves Comet developers implementing (and more frustratingly, debugging) several transports across several browsers. Traps are numerous and easy to stumble into.
event-source is the future of all Comet things.
Comet wrapper for the Mootools 1.2 JavaScript framework.
Cometd Bayeux is a publish/subscribe messaging system, and this has drawn some criticism that PubSub is not the most flexible paradigm for an Ajax/Comet transport.
After some recent optimizations, the Dojo Cometd implementation of the Bayeux protocol running on the Jetty web server can now handle up to 20,000 simultaneous users per server while maintaining sub-second latency.
impressive numbers. Does the Twisted one can beat that?

Welcome to the lift Web Framework lift is yet another web development framework. lift runs inside a Java web container and uses the Scala programming language for coding. lift stresses security, developer productivity, ease of deployment, ease of maintainability, performance, and compatibility with existing systems. lift borrows from the best of existing frameworks including Seaside's highly granular sessions and security, Rails fast flash-to-bang, Django's "more than just CRUD is included", and Erlyweb's scalability for Comet-style applications. lift is built on Scala, a hybrid Functional and O-O language that compiles code down to the Java Virtual Machine. Scala code can call any Java code and make use of all Java classes. Java code can call some Scala code. lift applications are packaged as WAR files and can be deployed on any Servlet 2.4 engine (e.g., Tomcat 5.5.xx, Jetty 6.0, etc.)
Comet is a software concept that enables web servers to send data to the client program (normally a web browser) without having any need for the client to request it. It allows creation of event-driven web applications, enabling real-time interaction otherwise impossible in a browser.
The Xaja machine is full featured PHP Reverse Ajax framework. It enables the developer to escape the request/response model, and reverses the way you think about your web-application. Furthermore, the developer can push the data from the browser to the client easily.
