CORS

Cross-Origin Resource Sharing (CORS) allows you to specify websites hosted on other domains that can access resources from the FME Server through Ajax requests.

CORS is enabled by default to allow any host to access FME Server resources.

To disable CORS:

1. Click Load Template, and select Disable CORS.
2. Click Save Changes. (Or to cancel, click Revert Changes).

To re-enable CORS:

1. Click Load Template, and select Allow All Hosts or Allow Specific Hosts.
2. Configure the remaining settings as desired.
3. Click Save Changes. (Or to cancel, click Revert Changes).

CORS Settings Options

Allowed Origins: A comma separated list of hosts that are allowed access to the FME Server. An * allows access from any host. An * cannot be specified if any origins are passing credentials. For an example of how to specify the list of hosts, click Load Template and select Allow Specific Hosts.

Allowed Methods: A comma separated list of HTTP methods that may be used in requests from the allowed origins.

Allow Headers: A comma separated list of permitted request headers from the allowed origins. A request header is any custom header set by the browser JavaScript application through method XMLHttpRequest.setRequestHeader().

Exposed Headers: A comma separated list of non-standard response headers that are safe to expose to the requestor (initiated through the XMLHttpRequest.getResponseHeader() method). This information is returned in the Access-Control-Expose-Headers response header.

Pre-flight Max Age: Specifies how long, in seconds, the results of a pre-flight request can be cached by the requestor. This information is returned in the Access-Control-Max-Age response header.

Support Credentials: If TRUE, allows the requestor to include credentials to authorize with the FME Server, including cookies, HTTP authentication (tokens), or client-side certificates. This value is returned in the Access-Control-Allow-Credentials response header.
