This is used in response to a preflight request. | `"GET, POST, HEAD, PUT, DELETE, PATCH"` |

This supports subdomain matching, so you can use a value like "https://*.example.com" to allow any subdomain of example.com to submit requests. If the special wildcard `"*"` is present in the list, all origins will be allowed. | `["*"]` |
| AllowOriginsFunc | `func(origin string) bool` | `AllowOriginsFunc` is a function that dynamically determines whether to allow a request based on its origin. If this function returns `true`, the 'Access-Control-Allow-Origin' response header will be set to the request's 'origin' header.

:::note
If AllowOrigins is a zero value `[]string{}`, and AllowOriginsFunc is provided, the middleware will not default to allowing all origins with the wildcard value "*". Instead, it will rely on the AllowOriginsFunc to dynamically determine whether to allow a request based on its origin. This provides more flexibility and control over which origins are allowed.
