Enable Cross-Origin Requests (CORS)

How do I fix CORS (Cross-Origin Requests) errors?

You may encounter CORS (Cross-Origin Requests) errors when attempting to hit Composable services (for example, at localhost/CompAnalytics/) from a web app running on, for example, localhost:8080.

You can normally fix this by editing the web.config file.

Look in the install folder (e.g., c:\program files\companalytics\webapp\web.config)
Find the cors config key and add an appropriate entry

For the example above, the entry would be:

<add key="CorsAllowHosts" value="[http://localhost:8080;http://localhost;](http://localhost:8080;http//localhost;)" />
