allowDynamicBackends

Functionin experimental@fastly/js-compute 4.0.0
Deprecated: Use enforceExplicitBackends instead.

Control whether or not Dynamic Backends are allowed within this Fastly Compute service.

By default, Dynamic Backends are disabled within a JavaScript application as it can be a potential avenue for third-party JavaScript code to send requests, potentially including sensitive/secret data, off to destinations that the JavaScript project was not intending, which could be a security issue.

Note: This feature is disabled by default for Fastly Services. Please contact Fastly Support to request the feature be enabled on the Fastly Services which require Dynamic Backends.
