Globalization not workin in production

We currently have globlization set up and are able to switch between multiple languages on our development box.  However when we push the code to production it stays defaulted to en-US.  I have verified all entries in the web-config  are the same and database entries for setting the session variables are the same.  

When I output my session variable to the page is it correct for the change language.  But the
CurrentUICulture stay en-US  

Are there any server permissions or other factors that would affect this?  

Any help is appreciated.

<httpModules>
      <add name="CookieLocalizationModule" type="PDR.CookieLocalizationModule, PDR" />

<identity impersonate="true" />  
 <globalization uiCulture="auto" culture="auto" />



public void PreRequestHandlerExecute(object sender, EventArgs e)
        {
            string lang = null;
            PDR.Models.Currency currency = null;
            string currencyCulture = null;
            try
            {
                lang = HttpContext.Current.Session["Language"].ToString();
                currency = (PDR.Models.Currency)(HttpContext.Current.Session["Currency"]);
                currencyCulture = currency.CurrencyCulture;
                var culture = new System.Globalization.CultureInfo(lang);
                var cculture = new System.Globalization.CultureInfo(currencyCulture);
                Thread.CurrentThread.CurrentCulture = cculture;
                Thread.CurrentThread.12= culture;
            }
            catch
            { }
           
        }
