+#CORS Implementation 
+
+This sample demonstrates how you can use the CORS policy to 
+support browsers CORS request. 
+
+Cross-Origin Resource Sharing (CORS) is a W3C spec that allows cross-domain communication from the browser. 
+By building on top of the XMLHttpRequest object, CORS allows developers to work with the same idioms as same-domain requests.
+
+The use-case for CORS is simple. 
+Imagine the site abc.com has some data that the site xyz.com wants to access. This type of request traditionally wouldn’t be allowed under the browser’s same origin policy. 
+However, by supporting CORS requests, abc.com can add a few special response headers that allows xyz.com to access the data.
+
+As you can see from this example, CORS support requires coordination between both the server and client. 
+In the Add-CORS policy , there is a Access-Control-Allow-Headers where we have added an additional entry 'X-Custom-CORS' apart from standard Allow Headers . 
+
+
+
+# Configure 
+
+Update `/setup/setenv.sh` with your environment details
+
+# Import and deploy sample project
+
+To deploy, run `$ sh deploy.sh`
+
+To test via curl, run `$ sh invoke.sh` 
+
+Additionally you can test CORS with javascript. 
+Please edit the index.html file and look for org and env variable . Change it with your settings.
+
+Put it in any web server and access it as
+http://localhost/demo/index.html 
+
+
+Trace the functionality in API Management Portal .
+You will see two requests - The first one being the OPTIONS request and then the GET request.
+Look for Origin Header , OPTION request and some response headers set by OPTIONS request.
