Can be dataloader used between multiple requests?

[voodoo-dn]

There is a question about nature of data loaders.

Should dataloader be used between multiple requests? For example:

type User {
  id: ID!
  friends: [User!]
}

query {
   users: [User]
}

Request 1: resolve friends field for users (1, 2, 3)
Request 2: resolve friends field for users (4, 5, 6)

Dataloader receives ids from both requests: 1,2,3,4,5,6

Is it okay? Example from repository shows that dataloader created for each request in middleware.
