Rewrite rules

[orbicos4402]

Hello, could someone make some rewrite rules to make the following changes:

For example:
https://mydomain.com/login.html ---> https://mydomain.com/login
https://mydomain.com/register.html ---> https://mydomain.com/register
https://mydomain.com/acount_home.html ---> https://mydomain.com/home
https://mydomain.com/upgrade.html ---> https://mydomain.com/upgrade
https://mydomain.com/faq.html ---> https://mydomain.com/faq
https://mydomain.com/contact.html ---> https://mydomain.com/contact

If so thanks!
