Access Nginx variables from HTTP modules

[Paulo Silva]

Would it be Ok doing something like?

ngx_str_t variable_name   = ngx_string("request_id");
ngx_uint_t variable_name_hash;
ngx_http_variable_value_t *variable  = NULL;

variable_name_hash = ngx_hash_key(variable_name.data, variable_name.len);

variable = ngx_http_get_variable(r, &variable_name, variable_name_hash);
