How to route all IIS requests to my MVC app?

问题

I'm creating an MVC 3 app that manages business for client companies. When deployed, incoming requests should prominently feature the name of the client company; thus, http://hosteddomain.com/Excelsior/Home/Dashboard/3 should retrieve the home page for a user from client Excelsior.

Question 1: On the development server this works fine (localhost:28497/ClientCompany/...) because my RouteConstraint looks up the business name. However, when I deploy this, how do I tell IIS to send all requests to my app? As it is now, IIS will look for an app named "ClientCompany".

Question 2: Is there a better way to do this? For example, using URLs of the form ClientCompany.hosteddomain.com/SomeAppName/[pages...]. If so, how do I tell IIS to remap the requests to my app AND how do I get the name of the client company from inside the MVC app?

Meta-Question 1: Maybe a better question 1 is how do I make my app be the Default Web Site for IIS?

Thanks for insight Eric

回答1:

On Question #2, you can get access to the raw url from the HttpContext.Current.Request. You can find out anything you want from there.

I would setup Host Headers in IIS for a single application, then parse the url and do whatever you need to from there.

EDIT

The only domain name that needs to be registered is the TLD (Top Level Domain), so

subdomain.tld.com is just a sub domain that you need to make a DNS entry for and then setup the IIS Host Headers.

Have a look at this: http://technet.microsoft.com/en-us/library/cc753195(WS.10).aspx

Note that Host Headers don't work if you are using SSL if I remember correctly.

You need to Register Routes in your global.asax. You just define the pattern you want to accept and designate the controller and action parameters.
