Where to store global settings in filter

Server NGINX
1

Hi All:
I have some settings in a json file (not in nginx.conf file),
Currently, in my module filter function, I will open file, read file,
close file every time filter function is called.
I think this is not so good, so I think it’s better call a function
just one time, and save the setting in a global variable, but I do not
where is a proper position in Nginx module, Thanks!

It may be a good idea to read the json file while parsing
configuration. Such things are usually done either when
processing a directive which specifies a file to use, or in a
configuration merge callback.

E.g., XSLT filter loads stylesheets specified in the
ngx_http_xslt_stylesheet() function, which is called to handle the
“xslt_stylesheet” directive. See
src/http/modules/ngx_http_xslt_filter_module.c for details.
