If an application is being written that serves pages from an internal web server that will be making requests to the Rally infrastructure, there may be a failure due to CORS policy. The failure can be observed in the console of the developer tools in the browser that the application is being run in and will appear similar to the following error:
Access to XMLHttpRequest at 'https://rally1.rallydev.com/slm/webservice/v2.0/hierarchicalrequirement?pagesize=1000&fetch=FormattedID' from origin 'http://localhost:8080' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
