Lighter RSC component requests.

[isla-nicole-may]

Goals

1. Give finer control to the cookies and search params passed in RSC component requests.
2. Make Next 14 easier to use with AWS lambda deployments

Background

RSC requests, by default, send all the cookies relevant to the domain, and all the search params included in the client side URL.

Many applications use client side search params for client state management only, and many applications share authentication cookies across sub-domains. These factors can lead to bloated RSC requests.

Proposal

Allow greater control over what cookies and search params are shared with the server. Achieved via global configuration or component specific setup.
