Using mod ReWrite to redirect request with certain paramet..

Hello;

I want to capture, and redirect, URLs that contain certain parameters (after
the ?). I have been reading a number of articles (web pages) on mod Rewrite,
but can't seem to get it working like I want.

For example, I want to redirect all URLs with "wxyz" in them, such as:

a.html?p1=123,p2=qwerty,wxyz=4
b.html?wxyz=def

Is what I want to do possible?

If so, can someone point me to an article (web page) or two that I can read?
(the pages I've found so far have not provided me the info I need.)

TIA.

This can be done using mod_rewrite. The parameters after the ? are
known as the Query_string. Rewrite Rules can be written that are
conditional on query_string matching a regular expression:

RewriteCond %{QUERY_STRING} wxyz
RewriteRule (.*) <redirect URL>
