Implementing Server Push

Read about Server push here.
I want to push data to client from my web application in real time.
I was looking at TCP sockets as one of the options.
For HTTP I found a variety of frameworks for Java, PHP, Python and others over here. However I don't know whether any of these support Push.

What options and frameworks would you suggest for implementing Server push?
What language would you advocate for implementing the same and why?

I believe xmpp implementation is one which is being use by a lot of big companies but the common thing is to use a comet server as well.

a lot of implementation in python for thoses you can google around.

How about Orbited, it's very good and being used by Echowaves

khelll 2009-09-15 03:58:23

Since Orbited opens TCP sockets on a web server will I have to use VPS for it?..If I am using shared hosting, probably the web host may not allow sockets to be kept open and running...

I'm using Orbited right now, it's great!

If you are doing chat or subscription type stuff use stompservice and orbited.

If you are doing 1 to 1 client mapping use TCPSocket.

I can give you some code examples if you want.

My implementation has multiple clients connecting to my server and they would be connected maybe for days.. would TCP Sockets be better here if so what framework/technology would you recommend?

Kevin Boyd 2009-09-15 04:08:22

Do the clients need to communicate with each other? TCP sockets are nice if your server is sending tailored data to the client rather than the clients sending data between themselves or the server broadcasting data which the clients subscribe to.For the above situations use Orbited/STOMP/MorbidQ.Otherwise the TCPSocket is nice and you just write the server side socket stuff manually.Depending on the complexity of what your server needs to do I've heard of people using twisted to do some of the heavylifting on the sockets, but I've not yet done that.

DevDevDev 2009-09-15 06:29:09

The nice thing about the sockets is that you can write the server in whatever language you like.Personally I tend to use Orbited + Python + Django which works really nicely for me.

DevDevDev 2009-09-15 06:30:21

By TCPSocket do you mean the one in Orbited or the generalized Socket?

Kevin Boyd 2009-09-15 08:51:21

TCPSocket is the Orbited specific implementation of an inbrowser socket. On the server side you can use whatever socket stuff you want. Either directly or through another framework like twsited.

Comet is the protocol you want. What Comet implementation is best, is a harder call.

If you're OK with Java (or, I guess, Jython), or .NET (where IronPython's a possibility), I suspect (not having extensively tried them all!-) that stream hub must be a major contender. It'a typical "freemium" product -- you can get a free ("as in free beer";-) version, or you can try the pricey Web Edition, or the even-pricier Enterprise Edition; feature comparison is here (e.g., free edition: no https, no more than 10 concurrent users, no .NET).

Does Comet work or HTTP? Any Comet like implementation on TCP sockets?

Kevin Boyd 2009-09-15 04:10:02

Yes, Comet's based on long-held HTTP requests, which in turn of course run on top of TCP sockets. See e.g. http://en.wikipedia.org/wiki/Comet_(programming) for tbe very basics.

Alex Martelli 2009-09-15 04:38:22

Have you seen a good comparison of Comet implementations serverside? I am currently playing with http://cometdproject.dojotoolkit.org/

What about Ajax Push Engine?

Shoban 2009-09-15 04:36:15

Have you tried StreamHub Push Server?

DLauer 2009-10-01 23:49:12

Not really, Alex Martelli mentioned this in his post... but the free version only allows 10 concurrent users...right?

Kevin Boyd 2009-10-02 17:15:49

I'm personally biased, but I like WebSync, for IIS/.NET. It integrates with IIS, so no other server software necessary, just a dll to add to your project.

@Downvoter - reason?

Ok, I'm using ASP.NET with PokeIn comet ajax library on my project. Also, I tried Atmosphere under JAVA.. My last choice was PokeIn.. Because, only server push support is not solving the problems. You will need some kind of client to server object serialization and object life time management. PokeIn covered all these needs for me.
