How to configure IPython behind nginx in a subpath?
I had the same problem. I updated nginx up to the current version (1.6.0). It seems to be working now.
Server config:
location /ipython { proxy_pass http://ipython_server; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header Origin "";}
