Can we stop session reset if page reloads?

WordPress doesn’t use PHP sessions.

If you tried stating a session in your custom-written code, it’s not going to work as you’d hope.

There’s a plugin which will enable all normal session use: https://wordpress.org/plugins/wp-native-php-sessions/

But, depending on what exactly you’re trying to achieve, you may prefer to keep things clean/do it the WordPress way and use a cookie and store data in the database as user_meta.
