regex - simple .htaccess redirect : how to redirect with parameters?

Question

My goal is simply to redirect:

/jsn.php?parameters to http://www.site2.com/jsn.php?parameters

I tried with

Redirect permanent /jsn.php(.)* http://www.site2.com/jsn.php$1

Query string parameters are automatically passed, you simply want to do this:

Redirect permanent /jsn.php http://www.site2.com/jsn.php

The (.)* doesn't work with the Redirect directive, you were probably thinking of RedirectMatch, but either way, you don't need it. And also (.)* should be (.*), otherwise the $1 backreference would only get the first character.
