HttpContext.Current is null for bots

I have the following code in a class which is called by a .NET page (asp.net webforms during page_load event):

public static bool BrowserSupportsJS
{
   get { return (HttpContext.Current.Session["js_support"] != null 
   && ((bool)HttpContext.Current.Session["js_support"]));
}

This line throws an exception for any bot: googlebot, bingbot etc

The exception is: Object reference not set to an instance of an object and it is on the get accessor line. It looks like HttpContext.Current is null.

You should check the Session for null like so:

public static bool BrowserSupportsJS
{
   get 
   { 
       if(HttpContext.Current.Session == null)
           return false;
       return (HttpContext.Current.Session["js_support"] != null 
           && ((bool)HttpContext.Current.Session["js_support"]));

   }
}
