Could you write like this?

ResourceRequest resourceRequest(m_absoluteResource);
resourceRequest.setIsCacheAwareLoadingEnabled(...);
FetchRequest request(resourceRequest, ...);

This is to reduce unnecessary mutableResourceRequest() calls.

Done.

     request.setContentSecurityCheck(m_shouldCheckContentSecurityPolicy);
     SecurityOrigin* securityOrigin = document->getSecurityOrigin();
     setCrossOriginAccessControl(request, securityOrigin);
