Thanks for your immediate reply steve. 

But I just want to know whether we can log request and response headers in nginx, for more debugging. 

As far as code is concerned , we are using , it is running if we don't use nginx. 
Only when we use proxy pass, it is failing. 

One important point , we are using ajax on port 6400 and on port 6401 we have done ssl enablement. 

Can you please help me to debug this issue. 

Thanks in advance.

I'd've said that the code being delivered to each browser is exactly the same ( ok, not necessarily true but you have to force it to be different ), so would look at the accuracy of the html / javascript on the page as a first step. 

Try a basic hello world page and see if that is displayed ok...
