Does `fetchRequestHandler()` automatically opt out of /app Route Handler caching?

I noticed that Next.js always skips cache for my TRPC API Route Handlers even though the request URLs are identical and the cache/revalidate config calls for persistent caching. I feel confident it has nothing to do with the

fetch()

fetch()

calls within the Route Handlers as the same

fetch()

fetch()

calls are happening separately within SSR via

createCaller()

createCaller()

and are being cached within Next's Data Cache as expected. However, I just read this from Route Handler docs:

You can opt out of caching by: Using the Request object with the GET method.

And I see that

fetchRequestHandler()

fetchRequestHandler()

takes in the

Request

Request

as a param:

import { fetchRequestHandler } from "@trpc/server/adapters/fetch";

import { appRouter } from "@/server/routers/_app";
import { createContext } from "@/server/trpc";

const handler = (req: Request) =>
  fetchRequestHandler({
    endpoint: "/api/trpc",
    req,
    router: appRouter,
    createContext,
  });

export { handler as GET, handler as POST };

import { fetchRequestHandler } from "@trpc/server/adapters/fetch";

import { appRouter } from "@/server/routers/_app";
import { createContext } from "@/server/trpc";

const handler = (req: Request) =>
  fetchRequestHandler({
    endpoint: "/api/trpc",
    req,
    router: appRouter,
    createContext,
  });

export { handler as GET, handler as POST };

Does

fetchRequestHandler()

fetchRequestHandler()

automatically opt out of /app Route Handler caching? And if so, is there a way to enable caching? Thanks in advance Sadge_pray

Routing: Route Handlers

Create custom request handlers for a given route using the Web's Request and Response APIs.
