I want to make an app that displays new data whenever they arrive inside a folder via xml. I want to use html5 web sockets but I am confused on how it should be done. I am using xaamp on my machine for development. Do I have to install another server to use websockets? Is apache as it is compatible and if yes how do I make the connection with the client. Thank you in advance..
Your options are:
Use something like mod_websocket, as pointed out by Phillip Kovalev. Or pywebsocket. You could also try PHP WebSocket.
Use a dedicated self-hosted realtime web technology for realtime communication between server and client. If you do this you'll also need to define a way of application to realtime web server communications - normally achieved through message queues.
Use a hosted realtime web solution and offload the realtime push aspect of your application.
There are concerns about using Apache with this type of technology since this technology maintains long-running persistent connections between the server and client and Apache isn't know to be too great at this. So, the best solution may be to:
Go with a 2nd dedicated realtime web server in conjunction with using Apache as your application server
Use a self-hosted realtime web server that has the ability to handle many concurrent connections
Use a hosted service along with your Apache application server.
If you don't expect many concurrent connections or if you are just trying out the technology then it's possible that Apache alone will be all you need.
Look at mod_websocket. It supports latest and commonly implemented by browsers vendors protocol version.

Mixpanel is using "SoftLayer" which blocks all the request from IPs coming from Iran. Is there a workaround to redirect these request to IPs in another country to be able to bypass their filter and send the data to Mixpanel?
There are multiple ways depending on your configuration and platform
what is your hosting? If its shared then your options are limited but if you deployed your application on a dedicated server or VPS you can route your traffic via transparent proxies or through a vpn tunnel. And there are many services for that either!
for example Squid is a well-documented and easy to use service for that! But keep in mind that it works better on linux! you can read these articles for configuring a transparent proxy with squid: On Ubuntu, On CentOS
But given the circumstances I recommend using an open-source analytical system such as:
Matomo (formerly known as Piwik)
Open Web Analytics
Heap (a famous iranian event site (Evand) was using Heap)
You can connect through a VPN tunnel. It works the way that you connect to a computer somewhere else (in your case in another country) and then you connect from that computer to the rest of the internet. So from the rest of the internet it looks like you're somewhere else.
You can check out ProtonVPN, they have VPN tunnels through a bunch of countries.
I get to know that we can use List to make different rooms/lobby over server. I am new to server side development. I am bit confuse now. Like i need to make list(rooms) at server side. So which module I'll use to make server side code ? should i code using node js module of deepstream . Currently i have just connected to deepstream server and also connected rethinkdb and redis cache connector. So do i need to write a separate node module to do server side coding using node deepstream.io-client-js ? or do i need to implement a server over deepstream.io module?
it would be a great help if anyone can tell
When using deepstream, the notion of 'server-side coding' is less clear than in traditional http-based applications. Usually the client will communicate directly with the deepstream server, and often application logic can be defined directly in the client. Security is then provided by configuring Valve permissions and authentication in the deepstream config.
For cases where application logic cannot be handled securely on the client, we recommend setting up Data Providers. Here, one or more 'provider' servers will run a deepstream client and provide access to a resource through deepstream's RPCs (remote procedure calls) or using the Active Provider pattern.
I want to implement webrtc server in my project. I want to make my own webrtc server and deploy it in amazon server. How can I achieve this?
WebRTC is a peer-to-peer protocol so you don't need a server for this.
You will need a signaling server for session negotiation. How you'll implement this depends on the technology that you'll use - client side: polling, ajax, websockets, stomp etc and server side.
For STUN/TURN you can deploy an existing server or use RFC and develop your own from scratch.
#Adrian Ber is correct, you need a signalling server such as this one:
https://github.com/peers/peerjs-server
You can set one of these up on AWS
You'll also need some code on the client side. There is a matching javascript client library (which does most of the work) here: http://peerjs.com/
There are some examples on the peerjs web site - they either need to be run on your local machine or on https servers (browsers will no longer allow camera access over http)
Ignore the people saying that WebRTC is peer to peer only. There is no reason why you can't implement an application, run it on a server, and treat it as a 'peer' for the sake of webRTC when it is actually a server.
That said, we've looked into pulling the WebRTC implementation out of Chrome, but it is a huge task. Depending on what you want to do, you will likely only need to support a subset of WebRTC functionality (Data channel / unreliable for example if you're doing a multiplayer web game).
There might be a few implementations out there that have cropped up now, but last I checked there wasn't anything of note.
I'm writing a server that needs to serve many clients. The traffic is NOT http (but rather some proprietary protocol on top of TCP). I'm not very familiar with commercial web servers such as IIS and Apache. Can anyone tell me if it's possible to write some sort of "extension" to run on top of one of these platforms so that I don't have to write the logic for the sockets? Or perhaps there is another way (not IIS or Apache) of doing it which is better?
My server is generally going to behave as a web service (gets request, queries db, sends response) however there is one scenario in which it stays connected to the client socket and sends updates at a given interval on that socket.
It seems reasonable for it to be a way to do this in a way that I'd only have to write my logic without the general logic of a server. Any ideas?
Thanks!
Good question, and its also good too look to leverage an existing web server - you get scalability and stability, effectively for free.
I've never done this myself, but it should be totally possible in IIS (i recommend v7+ for this, makes it easier).
You can set up a new web site through the administration tool, and assign it a port to listen on - this bit is pretty straight forward. You should set its Binding Type to net.tcp (this is a dropdown in the dialog to add a new website, you can't miss it).
You can then use either modules or handlers to implement the rest of your custom functionality. This article Developing IIS 7.0 Modules and Handlers with the .NET Framework is a good intro to the subject. Most of the doco out there about writing custom handlers and modules is focussed on the HTTP protocol, but there are some snippets floating around for TCP and/or net.tcp (because IIS and Apache are web servers, and web is synonymous with http). Another resource that may be useful is this: Configure Request-Processing for a Web Server (IIS 7)
Alternatively, you may consider changing your approach and do it as a net.tcp WCF service, with this you get the benefits of using IIS, the flexibility of choosing the protocol (can be statically configured, doesn't need to be compiled in), and you don't have to write handlers or modules.
Does there exist anything similar to Pubsubhubbub for communicating between non HTTP servers (Thrift servers).
PubsubHubbub with HTTP and RSS is an over kill for my current setup.
Are there any existing solutions / approaches which try to achieve this?
If you are using Microsoft OS, you can use MSMQ
