问题
I am calling a method in server side using ajax. This server side method is a batch operation and it takes around 20 - 30 mins to complete. When I run the web site on Chrome everything works fine. Bur on Edge and Firefox the ajax error method is invoking after around 1 hour. When I enable the logs the server side method is completing without an issue. But the ajax success method is not calling. After the server side method complete, ajax call is still active and after some time ajax error method is calling.
Furthermore, I have tried after adding a large timeout to the ajax call. But the result is same. Also when I runs small batch operation(around 2-3 mins). This ajax call is working on all the browsers including Firefox and Chrome.
