Web content management frameworks are often integrated with external platforms, APIs, and services. When the external source is hosted on a different domain, CORS is used to allow requests from the external local domain to the target domain of the web content management framework, without needing a proxy. We will look at techniques for allowing these requests.
When making a CORS request from the web content management framework as the local domain to a different target domain, it is either handled with custom code using the methods we covered in the earlier chapters, or a plugin may implement the headers and methods needed for the requests.
