Issue nginx - ajax

[Vishal Mestri]

Hi B. R. 


Thanks for your reply and really sorry for the way we conveyed our request. 


We tried to use tcpdump command to trace the issue , but still we are not yet resolved the issue. 


Now we have distributed logging i.e. we are logging differently for port 6401 and we found that request is not forwarded in case of ssl. 


I am attaching here with logs generated. 


error-6401.log_chrom_21may - error log generated when we used chrome 
access.log_chrome_21may - access log generated when we used chrome 


access.log_ie_21may - access log generated when we used ie 
error-6401.log_ie_21may - error log generated when we used ie 


We went through the logs and concluded that , in case of ssl, nginx is not able to forward request to proxy server , when we use IE. 
But we are not able to understand , what is cause of the same. 


If any one can guide us , where exactly we are going wrong. 




Thanks & Regards,

I request all Nginx master/experts to help me. 




​That looks like an odd way to *ask* for help. 

If you wanna *request* help, consider getting paid support.​ But even doing that, that is rude... 


What the error says is that the '*backend* closed connection prematurely'... You should look into it when processing the crashing request. 


Based on the logs, for that request, nginx received different headers depending on using either IE or Chrome: 

IE 
"GET /Stream.html?s=0&d=%22168.189.9.09%22&p=450&t=1399381478365 HTTP/1.0

Chrome 
"GET /Stream.html?s=0&d=%22168.189.9.09%22&p=0&t=1399381806838 HTTP/1.0

Cookie? :o) 

Look into your application in the backend which does not answer when some conditions, the problem does not seem to come from nginx which forwards requests to yourf backend.
