My goal is simply to redirect:
/jsn.php?parameters to http://www.site2.com/jsn.php?parameters
I tried with
Redirec
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.
