Match controller action in htaccess

I want to add if condition in htaccess file for a controller action. The url is like

www.example.com/user/profile/5?cid=7&pos=1

I want to add condition in htaccess file if url is action "profile". I tried following:

<If "%{REQUEST_URI} == 'profile'">
        // do something
</If>

but it doesn't work. Please advice.
