what is the best format for locale in URL path param?
<p>plan is to add <code>{locale}</code> in path parameter of the url, locale values are expected to be "en-US, fr-CH". As per my understanding path parameters should be lower case and dash separated so i prefer to have it as "en-us" but as per locale standards it should be "en-US" with country in caps. what could be the better option among two lister below in this case &amp; share if you have any better option.</p>

<p><code>
Option 1: http://mydomain.***/en-US
Option 2: http://mydomain.***/en-us
</code></p>
