Detect browser javascript on and off in ASP.Net using c#

The value of Request.Browser.JavaScript indicates whether Javascript is enabled in browser.

The above method is depreciated. A better solution is as following (C#):

        bool bJavascript = Request.Browser.JavaScript;
        System.Version version = Request.Browser.EcmaScriptVersion;
        if (version.Major >= 1)
        {
            bJavascript = true;
        }

Javascript Hosted on Google Drive Not Working Reliably

It works perfectly, until a few days ago when I noticed that if the web page contains javascript files hosted at Google Drive, it can not be viewed properly from the Facebook built in web browser.  I did some further investigation. The same thing happened when the page is opened in Wechat built in browser.  However, the page works fine when it is opened in most browsers, like IE, Chrome, Firefox. It took me several hours to figure why. And So far I have not find out the reason. I checked the mime type of the files. They are correctly recognized by Google Drive. But the solution is: moving the files out of Google Drive. Now it works perfectly, in browser and in App built in web browsers as well.
