+# CrossOriginStrategy
+
+`CrossOriginStrategy` is a class exposed by @abp/ng.core package. Its instances define how a source referenced by an element will be retrieved by the browser and are consumed by other classes such as `LoadingStrategy`.
+
+
+## API
+

+### constructor(public crossorigin: 'anonymous' | 'use-credentials', public integrity?: string)
+
+`crossorigin` is mapped to [the HTML attribute with the same name](https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/crossorigin).
+`integrity` is a hash for validating a remote resource. Its use is explained [here](https://developer.mozilla.org/en-US/docs/Web/Security/Subresource_Integrity).
+
+
+### setCrossOrigin(element: HTMLElement): void
+
+This method maps the aforementioned properties to the given `element`.
