Description
### Command
run
### Description
It would be a useful optimization to cache some requests during SSR across requests to the SSR server. Some of the API requests have infrequently changing data. Pulling the response from cache would save a lot of network time, especially if the response is big.
Flow:
User 1 makes makes request to Angular SSR server -> SSR makes requests to API in order to gather data for rendering -> request gets cached -> user 1 receives an html response.
User 2 makes request to Angular SSR server -> SSR server would make API request in order to gather data, but instead pulls the response from the cache -> user 2 receives an html response.
One possible implementation would be to consider Cache-Control header and cache the response in the server for the time specified.
If this will not be considered - what would you say is the best approach in order to optimize these kind of API requests? Perhaps a wrapper around `global.fetch` in Node server (where Angular engine runs) which would monitor every API request and store in some local cache?

Contributor guide
Research direction
No files, tests, or concrete entry points are named. Start by tracing the Angular SSR/hybrid rendering request path in the Node server and reviewing how global.fetch is used; define cache scope, expiration, and Cache-Control behavior before implementation. Done would require an agreed design, implementation, and coverage for cross-request caching.
