Setting for Cache-Control to allow preflight requests to be cached in CDNs

Prerequisites

• I have written a descriptive issue title
• I have searched existing issues to ensure the feature has not already been requested

🚀 Feature Proposal

Add a cacheContol option to the settings which will set Cache-Contol header on preflight responses.

A number value would probably set Cache-Control: max-age=${cacheContol}, and a string value would set Cache-Control: ${cacheContol} (fully sepecify the header contents), and otherwise the header would not be set.

Motivation

There is a maxAge option for the Access-Control-Max-Age header. This typically allows preflight requests to be cached in the browser, however typically not by a CDN.

Example

No response
