Spaces is an S3-compatible object storage service that lets you store and serve large amounts of data. Each Space is a bucket for you to store and serve files. The free, built-in Spaces CDN minimizes page load times, improves performance, and reduces bandwidth and infrastructure costs.
Client web applications loaded in one domain can interact with resources in a Space with Cross-Origin Resource Sharing (CORS) configured.
To configure CORS for a Space, navigate to its Settings page. In the CORS Configurations section, click Add.
The Advanced CORS Options window that opens lets you set advanced CORS options, like allowed methods, allowed headers, and access control max age.
