The nginx directive fastcgi_split_path_info just sets some
internal-to-nginx variables.

To send things like SCRIPT_FILENAME and PATH_INFO to the upstream fastcgi
service, you will have some fastcgi_param directives that use those
variables -- in this case, presumably they are in the "include" file.

You can continue to use fastcgi_split_path_info to set some variables.

For uwsgi, you will need some uwsgi_param directives.

You may want to edit whatever default "include" file you use, or perhaps
write the directives directly.

You will want to know what parameter names your upstream uwsgi server
actually uses, and make sure to set those to the values you need.

Good luck with it,
