When a web page is not available, it shows default webpage not available error, I want to detect when a link is clicked if internet is available. Is this possible.

This is a cross platform way of checking network connection in Xamarin. It can also detect the type of connection currently active. It is very very easy to get up and running.
As for your solution - when that link is clicked, you can check for a network connection using the plugin then, if there is a connection proceed to the web view otherwise, display an error.

I have been writing Unit Test and UI Test in my app. I have completed the most part of it. The pending thing is the Network Retry view. This page will be called when there is no internet. Is there any way we can turn off internet access (WiFi) in runtime so that i can execute UI test cases to test this page? In other words, this page will be called in the dashboard if there is no internet. So for going to the dashboard, the app needs internet access(to login, etc). Once it goes to the dashboard, i should be able to turn of internet access from within my test case and then check the Network retry page.
Use Network Link Conditioner to control the internet connection
I have been trying to understand how Mobile Device Farms like DeviceConnect, AWS Device Farm, SauceLabs, etc. get to remote control iOS devices, but I can't find anything on the subject. They get to do it without jailbreaking, which baffles me even more.
I love these kind of projects, because at the moment it seems undoable, but I know that it is possible ('they' are doing it).
With remote control I mean: seeing the screen of the iOS device on your computer screen and able to touch and swipe with your mouse.
Can someone please point me in the right direction as to how these technically work?
If you're using an iPad (in particular) or an iPhone (if you think you'll be able to make our any detail on the smaller screen) then using remote access to view and control what's on your friend's Mac is a good option. And the best way to remote-access a Mac from an iPad is to use Google's free Chrome Remote Access service, which lets you remotely use Mac programs from an iOS device.
It's quite an involved process to set it up the first time, but easy if you want to do it again in future. You'll need the Google Chrome web browser for Mac, and a Google account.
Here is link for Chrome Remote access
https://chrome.google.com/webstore/detail/chrome-remote-desktop/gbchcmhmhahfdphkhkmpfmihenigjmpp?hl=en
Open Chrome and go to Chrome Remote Desktop on the Chrome Webstore. Click Add to Chrome, then Add App. Click Allow, then Continue.
I will give you one approach and small explanation .
You will need to create application with all possible permissions at first also implementation handlers functions .
For example :
Works with files
Real native Socket connections (not http protocol) + need to have some main server signalling (domain or static ip).
Handle remote touch trigger (main problem for real remote/iOS)
Background part experience
Your app need to be non-Market app (more likely).
You can make Application with all possible options that apple give us.
What can you do remote with your app : -control camera/ Mic read geo data , work with galleries , delete or create files . Socket will be communication line .
Also app must initially started and make (on user request) always allow all permissions .
Use camera :
Send with socket some command example ( openCamera ) . AFTER receive this string perform action for opening camera .
If you can fix programability triggering touch events you can make remoteIOS.

Sorry for the first quick answer,
All of these: DeviceConnect, AWS Device Farm, SauceLabs use Appium in order to control devices.
The component that execute the command is the WebDriver.
Appium have different WebDriver implementation in order to execute operations to different device.
The iOS WebDriver can be found here: https://github.com/appium/appium-ios-driver.
The protocol in use is the JsonWireProtocol.

I am trying to implement a splash page/ wifi landing page on my existing public wifi network, using the DNS method mentioned in Wiki, in which I host a custom DNS server, that will redirect ALL dns lookup to a local address where a web server is hosted, for all user before they click agree.
After the user clicked agree, my custom DNS server starts returning correct ip for the look up, thus, user will be able to get online.
note: We totally understand that this is in no way secure our network, and even putting our network at risk. But the goal here is to just to pop the landing page up in front of our users.
This approach actually works on Windows Phone (Windows 8 I tested) as splash page, and even on a computer when I try to open a random website, it redirects me to my page, and after I hit agree, I can get to the internet.
When I try it on iPhone/ Android, once I connect to the hotspot, the splash page/ wifi landing page appear as expected (because the device is trying to verify internet access by going to the set of pages) However, after I click agree, and allow internet access, both iPhone and Android splash screen will not go away. I have to force iphone to "use this wifi without network" to exit.
I wonder if there is a special (javascript?) method I can call in the page, or some package I need to send to the device? I noticed on iOS, if I click a link to the App Store, the splash page go away without disconnecting from the network, So, I guess I am missing something here.
For example, clicking the link to the iOS StackOverflow App on iOS device can be a workaround.
Had been googling around for a week now, nothing seems to came up.
by the way, I am building my custom dns server on node js, with the module dnsd.

I also uploaded a demo of my code on GitHub:
https://github.com/kylelam/dnsd_wifi
To test it, run it in your local network (sudo node demo.js). Then, change your phone's dns to your machine's IP. Disconnect your phone from wifi and connect to it again. (on iOS, you might need to go into detail, and enable auto-login, and auto-join, or if you can't, just reboot.)
*note1: the server will need to run on port 53, and 80, so it need sudo.
*note2: please don't laugh at my code, I'm very new to this. But please do point out.
*note3: you will need to npm install these packages: os, express, dns, dnsd
ttl set to 0 might be the cause of the issue, try a different value like 5.
My problem
I'm working on a project where Cordova is being used to display a remote website within the app. Cordova.js is being run from the remote server, etc., and this works pretty well.
I do have one issue though, especially on iOS devices.
If the device lose connection at the same time as I press a link on the website, the page will turn blank, as if to load the next page - but since the connection is lost nothing will be loaded into this blank page. Given iOS devices lack of back-buttons or such there's no way to navigate from this blank page except by closing the app and re-opening it.
My attempted, and failed, sollution
So, given that I can use Cordova.js to check for connection issues, I figured that I could use an iframe to display the remote website. If the connection goes bye-bye I'd just display a simple error message inside the iframe.
And well, this does work.
BUT. And this is a big but. InAppBrowser will not run from an iframe. And I can't live without the InAppBrowser, since it's used to display quite a few important features within the app.
So
Does anyone know a way to either:
a) Handle connection issues when running only remote content in the Cordova app?
b) Run the InAppBrowser from within an iframe? (I suppose I could use PostMessage etc. between the frames, but since I'm already sending/receiving data from the InAppBrowser I would love to avoid this in order to limit complexity).
c) Solve this issue in another fancy manner?
I'm not entirely sure why I feel this way, perhaps something I read at some point, but my understanding is that while providing an offline experience within an app, it is my responsibility to appropriately manage situations where my app requires an internet connection and one is not available (a proper alert for example).
When opening an external website using the Cordova InAppBrowser, if there is no internet connection, am i required to do something about it, or is the error appearing in the webview of the plugin enough? Will this interfere with the approval process, or is this entirely ok?

point 4 seems to point out that apps (games here) may get rejected if connection issues are not properly handled.
