What is the difference between %1 and $1 in .htaccess?
For example,
# to remove www
RewriteCond %{HTTP_HOST} ^(\w+)\.mydomain\.com [NC]
RewriteRule .* [R=301,L]
# versus
# RewriteRule .* [R=301,L]
I have been using Dave Child's .htaccess cheat sheet and Jackol's .htaccess cheat sheet as well as the Apache mod_rewrite docs but additional help would be great.

%1 Refers to a pattern matched in a RewriteCond condition, while $1 refers to a pattern matched inside a RewriteRule.
More generically, use %n to refer to the numbered matches from RewriteCond condition regex patterns, and use $n to refer to numbered matches from RewriteRule regex patterns.
