+## Custom pre-fetch HTTP Verb
+
+Some services (such as AWS) provide URLs that works only for one pre-configured verb.
+By default, `react-doc-viewer` fetches document metadata through a `HEAD` request in order to guess its `Content-Type`.
+If you need to have a specific verb for the pre-fetching, use the `prefetchMethod` option on the DocViewer:
+
+```tsx
+import DocViewer, { DocViewerRenderers } from "react-doc-viewer";
+
+<DocViewer prefetchMethod="GET" />;
