How to enable Cross-Origin Requests in ASP.NET Web API 2

According to Msdn, Cross-origin resource sharing (CORS) is a World Wide Web Consortium (W3C) specification (commonly considered part of HTML5) that lets JavaScript overcome the same-origin policy security restriction imposed by browsers. The same-origin policy means that your JavaScript can only make AJAX calls back to the same origin of the containing Web page (where “origin” is defined as he combination of hostname, protocol and port number). CORS relaxes this restriction by letting servers indicate which origins are allowed to call them. CORS is enforced by browsers but must be implemented on the server, and the most recent release of ASP.NET Web API 2 has full CORS support. With Web API 2, you can configure policy to allow JavaScript clients from a different origin to access your APIs.
CORS can be enabled using a Web API or OWIN Middleware. The one you choose to use will depend largely on your requirements. In this article, we will be implementing CORS using the OWIN Middleware. To …

Multitenancy contrasts with multi-instance architectures, where separate software instances operate on behalf of different tenants. By giving companies, access to a tenant through a subdomain of choice, will help to personalise the experience more and gives a sense of ownership to each tenant. This will go along way to bring consistency in there branding.
