I have to fix a bug where a single international user gets the wrong language and need to replicate this. As an admin, I can log in as the user. But I have no plans to switch my Windows language to Swedish. So I thought I would track down the exact line of code which reads the Default OS language and assigns that to my website to use.
Any idea what variable names I could search this very large solution for? I assume it includes "Environment".
What function would this be in? I will look inside Global.asax if there is one...
