.net WebApi 2.0 - Set culture for all the user request at code level (Globalization)

I have a .net webapi 2.0 using standard .Net Framework ( not core ).

In this moment the default Culture is set in webconfig:

web.config

<system.web>
    <compilation debug="true" targetFramework="4.5" />
    <httpRuntime targetFramework="4.5" />
    <globalization enableClientBasedCulture="false" uiCulture="it-IT" culture="it-IT" />
  </system.web>

What I wan't to do Is provide a method where the user can switch the culture. I'm trying this code but it doesn't work...

Thread.CurrentThread.CurrentCulture = new CultureInfo(strCulture);

The culture is changed only for that thread but for the nexts it continues to get the default culture specified in webconfig....

Thanks to support

This is what worked for me:

public class LanguageMessageHandler : DelegatingHandler
{
    protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        // here you can chose to get the lang from database, cookie or from the request if the culture is stored on local storage.
        SetCulture(request, "ro-RO");
        return base.SendAsync(request, cancellationToken);
    }

    private void SetCulture(HttpRequestMessage request, string lang)
    {
        request.Headers.AcceptLanguage.Clear();
        request.Headers.AcceptLanguage.Add(new StringWithQualityHeaderValue(lang));
        Thread.CurrentThread.CurrentCulture = new CultureInfo(lang);
        Thread.CurrentThread.CurrentUICulture = new CultureInfo(lang);
    }
}

Add the LanguageMessageHandler to MessageHandlers in WebApiConfig

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.MessageHandlers.Add(new LanguageMessageHandler()); // <- add this line
        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }
}
