I am thinking of adopting Loopback.io to create a REST API. I may need the following approach: an inTERnet server (run by me) to which clients connect, plus a fallback inTRAnet server to which clients connect only in case the internet connection is down. This secondary fallback server should then replicate data on the main server when the internet connection is up and running again. As clients are on the same inTRAnet they should be able to switch automatically to the fallback server. Is this possible as an idea and if so, what do you recommend i start digging into?
Thank you all!

Simon from my other account. I believe what you want is possible as you can use whatever client side technology you want with LoopBack. As for easy solutions, I'm not familiar enough with Cordova to give any insight there.
It is definitely possible, but I suggest going through the getting started tutorial first. You'd probably create two application servers and have another proxy in front to route the requests to server a or b based a heartbeat from the main server. You would have to code all the logic and set up the infrastructure yourself though.

I'm creating a video chat web app and I need to deploy a coturn TURN server somewhere. What I'm asking is do I need to purchase 2 droplets on Digital ocean, one for the TURN server and one for my web server or can I place them in the same droplet thus saving money.
Is there any good reason in buying 2 hosting spots, maybe performance issues?
Technically, you can deploy it at the same server. But you shouldn't.
There will be a time when you need to upgrade the turn server, i.e. the numbers of users are increasing. If you split these applications, the node server will not be affected, since it's not necessary to upgrade it.
Another example would be, that you want to use more than 1 turn server, for load balancing for example. Also in case of a problem, once application will not be affected and it's easier to integrate a replacement / backup server.
My advice would be:
yourdomain.com -> Main application
turn1.yourdomain -> Turnserver
turnX.yourdomain -> maybe an additional server in the future.
With that solution you can also make sure, that the turn server is not using all the bandwidth, so yes, that's the possible performance issue you mentioned.
Ok lets say I want to create a connection between my iPhone app and my server (i'd like to try and use GoDaddy servers for this) to server real time location data to users.
I've seen plenty of good stuff online about using sockets, streams, ASIHttpmessage, CFHTTPMessageRef, etc., but what I'm unclear about is how to set up a server that continuously servers real time data to users (I believe you'd need a stream of data going to the user for this, not just a single http request and response). How does one take a host like GoDaddy and run server code on it. I know you can set up a server like this using terminal, but I don't have access to command line or the ability to run this "server program" from my web host as far as I know. Is there software I can download on my cpanel for this? Do I need a virtual private server and different hosting via GoDaddy maybe?
Does anyone know how I can do this or if my understanding of this whole thing is wrong. Please keep in mind I need this real time (or close to). Please, educate me. I really just need a better understanding of how this works.
I'm trying to get into an implementation of some kind of push notification for a Windows WPF client application and a java backed server.
The idea is to avoid as much as possible polling the server, so I thought to implement it with sockets and messages, and relying in some easy pulling solution in case a socket connection could not be done, (Firewalls, etc).
In the other hand is important that the data traveling get encrypted.
So I have a couple of question/"request for opinions" more related with the WPF client:
Perhaps already exist some solution for that, any tips?
Could be good to think in some SSL sockets connections for that?
If 2 is OK, there is some native solution for secure sockets in .net or any library?
If sockets solutions is an option, I guess i need to go through port 443 and by the way it will avoid many problems with firewalls and so on, am i right?
I know there is many question but all are related to the same problem.
Thanks in advance.

Yes, SSL is good if you need to keep the data secure during transfer
Yes, http://clientengine.codeplex.com/ indicates it supports SSL/TLS
Well, it depends on whether you are controlling the server or not. If you have control over it you can use whatever port you want.
I have a perl web application (CGI::Application with ModPerl::Registry) which connects to a authenticated custom server over a socket and exchanges data (command/response) with it. Currently the web application connects to the server, authenticates and disconnects on every page request - even for the same user.
Is there some way I can use the same socket over multiple page requests which share a common session id? Creating a separate daemon that proxies connections and makes them persistent is an option I am exploring, but would like to know if there are any simpler solutions.
I have no control over the design of the custom server unfortunately.
Looks like the same question was asked on PerlMonks. The responses there point in the right direction, but the issue seems to be that you want one cached connection per session, not one cached connection per session per httpd thread/process. You might have to resort to a separate proxy process to get the behaviour you want.
I'm researching how to code an iPhone app that needs to connect to an online service to get data. The online service only provides access to specified IP addresses or ranges, so iPhones won't be able to connect directly, and the request will have to go through a server. I looked into setting up my own forward proxy server (which the service in question are happy with, by the way), which I guess would do the job for most other platforms. Unfortunately the iPhone does not seem to allow configuring a proxy address programmatically. Is there another potential solution for accessing the content from an intermediate server, that would show the online service the IP address of the server, rather than each individual iPhone?
Many thanks

It appears that using cURL is one way to achieve this. There should be bindings available for Cocoa.
I'll let people know how it goes in the comments.
