I'm working on application in JSF to processing XLS files. When time of process is longer than 5 minutes web browser returns 502 Bad Gateway error, but process is still working on the server side. The problem is because of outbound socket timeout (value of timeout can not be changed).
I tried using JavaScript and Ajax request in JSP page, but it still doesn't work.

JSP page code:

Please help.
