A library for .NET websites which provides configurable site-wide CORS request handling.
Browsers normally prevent webpages from dynamically referencing resources from domains other than their own. This is a security feature, and is usually not a problem. However, when you do need to go around this policy, the system for doing so is called CORS. CORS (which stands for "Cross-Origin Resource Sharing") allows you to specify certain domains which are permitted to reference resources from your server. This library implements that system, and provides a simple way to configure it for .NET websites.

Use NuGet to install this package.
On installation, this pacakge adds a section to your web.config, like so:
<corsConfiguration>
<rules>
<!--<add domain="example.com" policy="ALLOW" />-->
</rules>
</corsConfiguration>Create a rule in this section for each external domain you want to allow access, and save the file. Changes are reflected immediately and automatically for every url on the site.
