Ember 2 Routing Subdomains - ruby-on-rails

I have a Ember 2 application (ember-cli) that uses a Rails API as the back end. For this application, I have enabled Wildcard DNS with my DNS Provider (Cloudflare). When a user signs up with my website, I want them to be able to use their subdomain to access their public home page.
For example:
A user named Steve signs up for my site located at awesome.com. So Steve browses to steve.awesome.com, which internally would translate to awesome.com/users/steve. How do I setup my Ember routes such that it can route based off of the subdomain?

I have come to a solution, but it isn't exactly what I was initially looking for. I realized there really isn't a reason why the URL has to be awesome.com/users/steve, and instead have decided that their subdomain (or custom domain) will act as their identifier. So let's say Steve browses to steve.awesome.com, I will figure out the host via window.location.hostname, and use that as a lookup key to pass to my Rails API and retrieve user data.
Not exactly the solution I originally was seeking, but it solves my issue!

How do I set up a Rails page as a subdomain of another site?

We're trying to create pages in our Rails app that will eventually live on a subdomain of another partnering site. This would be like StatusPage, which allows users to create a status page with their account on the StatusPage site and then attach it to their own subdomain (e.g. status.usersite.com).
For example, if we wanted one of our pages (www.oursite.com/users/bobsplumbing) to be a subdomain on another site (ourservice.bobsplumbing.com), how would we go about it?
If it's useful info, we use Heroku to host the Rails app and we also utilize Route 53 and Cloudflare.
From your example I understand that you want to have multiple web apps since that would be your customer domain and your page will redirect to that page.
You will be better off to do NGINX (or whatever you use) redirects since they are faster and will take less time, being cached by the browser after the initial load.
To answer your question you can add this code to your routes:
sites = %w(bobsplumbing catsandboots)
sites.each do |name|
match "users/#{name}" => redirect("https://ourservice.#{name}.com")
end

Redirect multiple domains to same azure website with custom parameters

I have a scenario where I have a web site that will be used by multiple customers.
But I do not want to publish the web site to each customer domain's. Instead I will publish the web site to an azure web site for example mywebsite.azurewebsites.net and I want all the customers domains to redirect to this mywebsite.azurewebsites.net but I need to know which customer is this so I can display the correct content. for example I am thinking about appending or sending a hidden custom parameter in the query string or such.
What I need to know is
How can I redirect all the domains to mywebsite.azurewebsites.net
How can I pass a hidden parameters in the redirect for example any request from the customer domain e.g "www.cust1.com/Home/Index" will be redirected to "mywebsite.azurewebsites.net/Home/Index?username=testuser" and "www.cust1.com/Home/Index?querystring=ffff" to "mywebsite.azurewebsites.net?querystring=ffff&username=testuser"
I do not want to publish any web site content on the customer web site that means the customer domain root directory will be empty.
There are quite a few different ways you can do this.
The first thing you need to determine is: How are you going to handle the redirection to mywebsite.azurewebsites.net?
Are you going to place code directly on the customers website to
redirect?
Do you have the access to the customers DNS's allowing you to forward their site to mywebsite.azurewebsites.net?
Do you want to create a CNAME record and point it to your Azure Website?
Method #1
If you have access to the customers website then this becomes the easiest method.
As you described above, I would simply redirect the user back to your site with some type of custom url i.e mywebsite.azurewebsites.net/customer1 .
When the user hits this page you could then set a cookie in their browser so that you know where they came from and then redirect them to the home page at mywebsite.azurewebsites.net. This would happen almost instantly and the customer would never notice.
Method #2
If you are able to forward the domain or they can only redirect the user to the main website at mywebsite.azurewebsites.net, you can simple look for the referring url when the request comes in. Then as you do above, based on the referring URL you can then set your cookie and show the proper content.
Method #3
This is assuming you have access to the customers DNS records and are able to create a CNAME record for www.customerwebsite.com -> mywebsite.azurewesbites.net
In that case, when the user visits the site you would just pull down the HOST and then set your content based on that.
The specific code is here:
string url = HttpContext.Current.Request.Url.AbsoluteUri;
// http://localhost:1302/TESTERS/Default6.aspx
string path = HttpContext.Current.Request.Url.AbsolutePath;
// /TESTERS/Default6.aspx
string host = HttpContext.Current.Request.Url.Host;
// localhost
You can find more information here: How to get the URL of the current page in C#
Let me know if you have any questions or end up implementing any of these solutions.

Rails, Devise, and multiple domains

Let's say I have an application that's going to be accessed from completely different domains that all point at the same server*:
example.com, example.net, foobar.com, ...
I have a Devise based authentication system that's worked fine before. However, the goal is now to add HTTPS to the sign in system. The problem is, as it turns out, there is no way to host more than one HTTPS website on the same IP address**. To resolve this problem, I set up the login pages to always POST to https://secure.example.com. As far as I can tell, this is working fine. Devise seems to have no qualm with it. However, the tricky part is that the user now needs to be redirected to foobar.com, which also needs to understand that the user is logged in. I pass the site to return to in a hidden parameter in the login form, and the redirection works fine. I still have no way to inform foobar.com that the user is now logged in.
I've managed to set it up so that, upon being returned to foobar.com, it copies the user's session cookie for secure.example.com into a new cookie for foobar.com. This part is working fine. However, in the Rails console, the web requests for secure.example.com and foobar.com - with the same cookie sent for each - produce two completely different sessions and therefore, it's no wonder Devise acts like the user was never logged in to foobar.com
Does anyone know why this wouldn't work - why two identical web requests (only the domain of the request URI was different - I tried it in Firebug, too) would produce two completely different sessions in a Rails 3 app with different, yet consistent, session ids? More to the point, does anyone know how to MAKE this work?
* assume, for the purposes of this exercise, that this is unavoidable and the sites cannot be hosted all under different subdomains, and that the number of domains required is too great to get a separate IP address for each.
** unless they're subdomains and you have an *.example.com cert, but that's beside the point.
If you're already using Devise, I suggest you try using token authenticatable. You can generate a token for the user in question, redirect them with the token to sign in, and then quickly expire the token after they have signed in.
You could also try rolling your own OAuth provider with doorkeeper.

Rails 3 custom domains for users on Heroku

I'm looking to set up custom domains for users. Much like Tumblr does.
I understand that the user must point their A record to an IP address. I found some information here: Custom domains in a Rails App
Can someone give me an example of this with a Heroku/Rails 3 setup? Is it even possible?
If you setup a wildcard DNS to point to your main app, you can use the :subdomain in config/routes.rb to handle your business logic.

IIS 7: Redirecting from non existing subdomains to a subfolder

I'm working on an ASP.NET MVC Multi Tenancy app.
Right now I managed to create dynamic subfolders, for instance some one registers with username "bob" and gets the following website:
domain.com/bob
My next goal is to provide subdomains: bob.domain.com instead of subfolders.
I found out that it's very complex to create dynamic subdomains with ASP.NET and DNS WMI. Is there a way to tell the server that it has to redirect/rewrite from bob.domain.com to domain.com/bob ?
In regards to routing based on subdomain, you should reference the following SO post.
**Sorry, I normally don't like to just link to an answer, but in this case, I don't want to take the credit from the original poster for the solution*
EDIT
Check out solution 2 to follow up on my comments below as a working example. You can ignore the ISAPI rewrite as the MVC routing engine would do this for you given the above solution from SO. Below is a snippet that you might find useful:
Setup DNS Server
Add the following entry into your DNS
server and change the domain and IP
address accordingly.
*.example.com IN A 1.2.3.4 Setup the Web Server
We are assuming that you already have
a web site created for your main site:
www.example.com. So let's just double
check to make sure it will be able to
accept all variations of the
subdomains.
* Open IIS Management Console and select your web site.
* Right click on it and select Properties.
* Click on Web Site tab.
* Click on Advanced button.
* Make sure there is one entry under the Multiple identities for this
Web Site with Host Header Name field
blank. This entry will intercept all
requests that comes to this IP
address.
* Make sure the IP address is only used by this web site.
