CORS Protocol Support

Add CORS (cross-origin resource sharing) Support behavior to the property that contains the protected resource you're calling from another domain.

Why you need it

If you use the Bot Manager Premier's inline telemetry feature to cover cross-domain requests, you can add the CORS Protocol Support behavior to the property that contains the protected resource you're calling.

How it works

Add this behavior to the property that contains the protected resource requests call from another domain.

πŸ“˜

This behavior requires allowing requests that use the OPTIONS method. See the Allow OPTIONS behavior.

Implementation

How you set up CORS Support behavior depends on whether requests originate from the same domain or a different domain, and whether protected requests are HTML form submissions.

Request originBehavior setup

Same-domain HTML form submissions

Add the behavior with no setting changes.

Cross-domain HTML form submissions

Add the behavior with no setting changes.

Same-domain non-HTML form submissions (AJAX requests)

Set up CORS Support in the behavior to allow credentials.

Cross-domain non-HTML form submissions (AJAX requests)

Set up CORS Support in the behavior to allow the Akamai-BM-Telemetry header. Allowing credentials is not necessary.

For more details, read about this behavior in the Bot Manager Help.
