Stripping out query parameter?

[Neil Sheth]

Ok, that seemed to mostly do what I wanted, thanks!

A couple things -

 I want to avoid writing the trailing '?' if there is no leftover
parameters to pass through:
www.mysite.com/test.php?extra=yes goes to www.mysite.com/test.php?
instead of www.mysite.com/test.php

Similarly, with multiple parameters, it seems to leave the final '&' on the end.

Do I need to create special rules for each of these?  Or, can I add
logic to test the content of $stripped_params and set the rewrite
accordingly?

Also, I'm not clear, where is it most appropriate to place this rule -
under server, or under location / ?
