changing extension of .sql files

[rebred]

how do I change the extension from .sql to .sqldemo ?

You can use a reverse proxy with url rewriting for that.

See the SQLPage nginx configuration guide for reference.
In your case, you may want to write

    location / {
        rewrite ^(.*)\.sqldemo$ $1.sql last;
    }

But out of curiosity: why are you doing this? What are you building?

Thank you we may remove the extension and leave it blank. One of our customer asked to build a shopping cart. Do you think it would be duable in SQLpage ?

Yes, it sure is doable!

Check out our authentication example to track user sessions, then create a shopping card table with a reference to the session id.
