## Interface ResourceIsolationPolicy

- All Known Implementing Classes:
    StrutsResourceIsolationPolicy
  Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

      @FunctionalInterface
      public interface ResourceIsolationPolicy

  Interface for the resource isolation policies to be used for fetch metadata checks. Resource isolation policies are designed to protect against cross origin attacks and use the `sec-fetch-*` request headers to decide whether to accept or reject a request. Read more about Fetch Metadata. See `StrutsResourceIsolationPolicy` for the default implementation used.
