reverse proxy is not getting JSESSIONID or userLocale cookie

[muhammad.nadeem714]

I am setting up a .net core reverse proxy under which i want to show japerserver-pro reports. i have setup test.dekon.no/jasperserver-pro/....... path under the application to reverse proxy to jasperserver-pro server. SO when i make request to test.dekon.no/jasperserver-pro/j_spring_security_check?orgId=***&j_username=***&j_password=*** in the browser, my middleware forwards that request to http://192.168.***.***/jasperserver-pro/j_spring_security_check?orgId=***&j_username=***&j_password=***. The response that i get in the middleware doesn't contain any cookies at all in the header. i.e. JSESSIONID and userLocale cookies
When i directly go to http://192.168.***.***/jasperserver-pro/j_spring_security_check?orgId=***&j_username=***&j_password=*** from browser from within network(VPN), these cookies are set and i am able to see reports and do everything. what am i missing here?
