Apache Redirect Question Mark HTTP Query?

[JAB Creations]

I used to handle folks connected via dial-up connections by directing them to a /du/ equivalent directory though now I want to setup a redirect match using an HTTP query. I read someplace that question marks aren't part of URLs (in Apache or?)...how do I set the following redirect. Right now it redirects to...
http://www.example.com/%5c%3f%5cconnection=0

RedirectMatch \/*\/du\/ http://www.example.com/\?\connection=0

you can look at the query string in a rewritecond, group the relevant part(s) and backreference it(/them) with %1(, %2, ...) syntax.
i know this works with rewriterule so i am assuming it also works with redirectmatch, although you should check the apache doc...

I'm completely confused. What does %1 translate in to?

I read the whole thread, most of the pages linked in the thread, and nothing has been broken down to essential parts; so I'm left without knowing what I need to use to construct the argument. Isn't there just a simple key table of some sorts available for Apache commands?

Basic required reading:

Rewrite rules:
RewriteRule [httpd.apache.org]

Conditional execution of Rewrite rules:
RewriteCond [httpd.apache.org]

Set-up to use Rewrite Rules:
RewriteEngine [httpd.apache.org]
