TLocaleMiddleware Class

Middleware that performs locale negotiation based on the Accept-Language HTTP header.

Remarks

This middleware parses the Accept-Language header from incoming requests and determines the best matching locale. The selected locale is stored in the request context and can be retrieved using Context.Item<ILocale>. The middleware also sets the Content-Language response header to indicate the locale used for the response.
