For multilingual asp.net mvc web site. 

Where should i set thread's culture to default language (which is tr-TR for my case), in addition i need to save this in cookie if it does not exists. in Application\_Start() or else ?

I have multiple sites(domains), so i need to change default language site specific.

```
 example.com must set default culture to tr-TR
 example2.com must set default culture to en-US

```
