allowDynamicBackends

info

This method is deprecated, and dynamic backends are now always supported when enabled at the service level. See enforceExplicitBackends instead.

The allowDynamicBackends() function is used to control whether or not Dynamic Backends should be allowed within this Fastly Compute Service.

By default, Dynamic Backends are enabled, but can be a potential security concern since third-party JavaScript code may send arbitrary requests, potentially including sensitive/secret data, off to destinations that the JavaScript project was not intending.

Using allowDynamicBackends(false) this security property can be restored to only use explicit backend definitions.

Note: By default, while dynamic backends are allowed in the SDK, they are by default disabled at the Fastly service level.
