server-push

Well, I have doubts about this technology, more precisely in its implementation, can not find good examples on the Internet, as it involves javascript and php, only, you would have some links where I can find this stuff really works and that ? leggetter A great source for all things Comet is Comet Daily . Unfortunately it's not updated all that often any more but there are some fantastic old articles in there. It's contributed to by guys that have been developing Comet solutions for over 10 years. Comet seems to get incorrectly bundled as meaning just one particular connection mechanism is

I'm looking for one that can be used to handle many long poll clients and does not create a thread for each request. Each call to IIS (ASP.NET) page works on its own thread. A good library should not create some extra threads. So, I'm using PokeIn inside my solution(online learning) and it doesnt create extra threads. It has a free community edition but not an open source :( you can check the source code for Pokein here edit It seems that the latest source available isn't that up to date, my bad. Check out their website instead. I've been using it 来源： https://stackoverflow.com/questions

I am willing to implement a chat website on App Engine. But I found that App Engine will not allow me to go with server push. (as it will kill the response after 30 sec). So whats the other method that can be used? Will polling cause bad user experience? Meaning will the user have to wait for some time to retrieve new messages from the server? What will be the ideal polling interval? If you use very small polling intervals, will my bandwidth get exhausted? Will I suffer performance problems? This is a quite old question now, but I was looking for a similar answer. I think the Channel API (

I'm trying to implement the Http2 push server functionality using "PushPromise" .NET 4.6.1, for this I have a "html extension" with Razor (we did not implement MVC only used the Razor engine to build the pages). public static IHtmlString PushPromiseStylesheet(this HtmlHelper htmlHelper, string src, bool addDomElement = true) { var context = HttpContext.Current; var path = System.Web.Optimization.Styles.Url(src).ToString(); var headers = new NameValueCollection { { "accept-encoding", context.Request.Headers["accept-encoding"] } }; context.Response.PushPromise(path, "GET", headers); var

I've been trying to get this long polling script to work but I keep getting stuck. This time I have a problem with the ajax request to the server. The php script that serves the data (running the long-poll using a loop and sleep) works perfectly fine but my jQuery script doesn't. So far I've tried using a normal $.ajax() request and a $.post() request to the script however when I do so the entire script stalls. Well the script actually loads like it is supposed to but the page shows that it keeps loading (using google chrome it shows the "waiting for" bar at the bottom of the screen). After

I'm trying to create a logger for a GWT application as an exercise to evaluate GWT. What I specifically want to do is have it so that I can post messages to a client side label at any point from the server side. So, if some interesting stuff has happened on the server the client can be updated. My First question is, is this possible, I can understand it not being. Second, if it is possible, where should I look for information, I've tried google and their documentation and all the showcases have nothing on this. Thanks Well, there are a couple of Options. You need to get the data from the

I am building a distributed system that consists of potentially millions of clients which all need to keep an open (preferrably HTTP) connection to wait for a command from the server (which is running somewhere else). The load of messages / commmands will not be very high, maybe one message / sec / 1000 clients which means it would be 1000 msg/sec @ 1 million clients. => it's basically about the concurrent connections. The requirements are simple too. One way messaging (server->client), only 1 client per "channel". I am pretty open in terms of technology (xmpp / websockets / comet / ...). I am
