detectBrowserLanguage + Caching

[warflash]

Describe the feature

In order to be able to cache responses from nuxt people basically all need to disable detectBrowerLanguage. This however makes it always default to the locale specified in nuxt config - even for recurring users.
I'd like to propse a middle ground:

• No locale in URL + no i18n_selected cookie in request -> default locale
• No locale in URL + i18n_selected value is set -> i18n_selected is returned as redirect url
• Locale in URL + i18n_selected is set -> return 200
• Locale in URL + no i18n_selected cookie in request -> return 200 and on client perhaps set i18n_selected

The important part is not returning a cookie from the server for cachability, but instead setting it on user interaction/navigation client side.

Hope that makese sense, if there's a way that's already possible then I'd love to know about it! Thanks!
