@welisonmenezes thanks for contacting us.

Can you trace who's requesting each file twice? I suspect is the service worker you have in the page installing the app. I would suggest you add caching headers to your images to prevent the multiple requests hitting the server.

@javiercn thanks for your answer.

I am running the application locally for while. I've just noticed the behavior that I mencioned before. It looks the images are loaded from server side rendering before, and after the blazor wasm is ready on the client side the images are requested again.

@javiercn But I guess after I configure the caching it might be solved. Thanks.
