I am using a rental server of general settings, nothing special, I think.
I did no configuration of the web server.
I did not changed anything on setting when installing the web site.
Thanks to all of you related,
I have uploaded the page.
when you click "パラメトリック" - which means "parametric"- tab,
you would see the list of our parametric designs, and again when you click a design,
you would link to the page includes openjscad model.
