I want to avoid nginx overhead (especially if they have tons of alias and rewrites) for in-server communication. Basically, you can have sveltekit server, backend server and nginx server, in that case, communicate inside your internal network will be very expensive like: browser->nginx server(10.0.0.1)->sveltekit server(10.0.0.3)->nginx server(10.0.0.1)->backend server(10.0.0.2) instead just: browser->nginx server(10.0.0.1)->sveltekit server(10.0.0.3)->backend server(10.0.0.2)
