I'm trying to implement comet in my ASP.Net MVC 2.0 project. I'm using WebSync from FrozenMountain. My website is coded in C# 4.0 and ASP.Net 4.0. The comet code is triggering my MVC controller function with the [HttpPost] attribute (even though the page doesn't refresh or appear to post). Is there a way to determine what is being post...
Which native server is best, in your opinion, to implement long-polling / Comet? The first target application is chat, but there will be other implementations - we basically need push-to-client capabilities. I'm limiting the answers to C# or Java because these two technologies are dominant at my workplace. The requirements are as usual:...
This is the node-chat I'm inquiring about: http://github.com/scottgonzalez/node-chat How are the messages being passed to the server? websocket comet ajax? How does it work? Is what it's using scalable? Thanks. ...

Hi. I'm experimenting with Comet and I'm stuck with implementing it via a hidden IFrame ("forever frame". This is my index.html: <!DOCTYPE HTML> <html> <head> <script type="text/javascript"> cometResponse = function() { var debugOut = document.getElementById('debugOutput'); return function(response) { ...
The Nginx approach to HTTP PUSH is relatively simple. There are 3 party involve: Subcriber (receiver), Publisher (sender), and the server itself act as multicast server. Nginx can also separate into different channel with different channel ID that user can access. But I still don't know how to authorize/limit content only for logged in...
I have a website using iframe comet, most of the users have no problem using it at home. However for a lot of user that use the website in office, the streaming data seems unable to reach the client. Could it be possible that the corporate firewall block this kind of long persistent connection to port 80?? Any suggestion to solve this pr...
Whenever I disable the APE comet Server, AJAX file uploads run properly. And when enabled, the response.responseText from PHP is not parsed. This problem has been bugging me since about more than a month. There's another person here with the same problem: http://stackoverflow.com/questions/3012636/can-not-use-ajax-upload-because-of-ape...
I wonder why it's so difficult to set up a server for live notifications with Comet. Will this ever be implemented in existing frameworks like Rails? It's popularity is huge, but it's still not easy to get it up and running. What options are there for Rails applications today? Thanks ...
I have a javascript-based client that is currently polling a .NET web service for new content. While polling works...I'm not happy with this approach because I'm using system resources and creating overhead when there aren't any changes to receive. My question is how do I notify my client(s) that there is new content for it to displa...
I'm exploring using Scala with its Comet facilities for my next project and was curious if anyone had experience using Comet (not necessarily Scala) with: WebOS Android iOS All these phones are WebKit, which should mean that my Firefox tests would work equally well, but I don't know how long-polling connections work over 3G (or wheth...
Hi, When deploying our portlet in liferay with glassfish set up with comet support enabled we get malformed http responses - seems like requests are not corelated with responses. For exemple - for an http request for a css we may get a image back that was requested by other http request. Our portlet is a jsf enabled portlet using JQuer...
Hello, I would like to write a simple server-push implementation either using long pooling or comet that integrates into the server. I don't want to use a networking framework like twisted because I want to learn how everything is done internally. What exactly should I learn? What specifications should I look at? I prefer something that ...
So I have a website already set up, and I need a comet server for a chat application. The site is built with twisted.web, and I want to build the comet server with twisted as well since I'm already somewhat familiar with it. But I'm not sure how to do it. I've looked at this post and understand the mechanics in the code snippet -- but I...
It looks like Websockets in HTML 5 will become a new standard for server push. Does that mean the server push hack called Comet will be obsolete? Is there a reason why I should learn how to implement comet when Websockets soon (1-2 years) will be available in all major browsers? Then I could just use beaconpush or pusher instead till ...
I know that Comet long polling are bad for Web servers because they occupy one thread per connection. So you cannot have a lot of users with persistent connections or your web server will crash. Is this the same with web sockets in HTML 5? How could this solve the resource problem if it occupies one thread too per persistent connection...
Is it possible to notify a server (make a single HTTP request with a bit of data, response is unimportant) when client leaves the page? I'm actually using python-tornado comet application with javascript constantly keeping a request connection to the server (which gets closed and re-opened on event. Based off this: https://launchpad.net...
I'm currently writing a simple cross platform app with Node.js on the server and web/iPhone/Blackberry clients. Bandwidth and latency requirements are similar to something you would see in an IRC "party game" or any chat system. I've developed the web client using http long polling (speaking JSON both ways). For iPhone/blackberry I coul...
