Hot damn! This bit of rewrite voodoo made my day! I’ve been looking for the same answer w/o any luck and this worked like a charm. Thanks a lot!

Great solution, BUT – it seems that using this I can’t access to the atoms defined in the RewriteCond with %1, %2, etc.

Sometimes the skip rule is written like so:

RewriteRule .? – [S=n]

That essentially takes care of the same thing as an asterisk, i.e. it allows “nothing” for the pattern which is likely the key issue in your configuration. Your situation may occur when you’re matching [with a RewriteRule] a URL without a path (e.g. http://www.somedomain.tld). Since a period requires at least one character, a rule without a question mark (“zero or one times”) or an asterisk (“zero to unlimited times”) attribute would be skipped and so the rules immediately following would be executed.

This worked great, except for

RewriteRule . – [S=x]

Instead, it must be

RewriteRule .* – [S=3]

I don’t know if it worked for the above users, but for me, using just a period (.) resulted in the following RewriteRules being used, until I changed it to .*

Perfect!
Using this trick to rewrite PNG images to JPG/GIF alternatives for IE6 browsers.

RewriteCond %{HTTP_USER_AGENT} !MSIE\s+6
RewriteRule . – [S=4]
RewriteRule ^MAIN_logo\.(png|gif)$ /images/MAIN_logo.jpg [NC,L,R]
RewriteRule ^MAIN_bg\.jpg$ /images/MAIN_bg_ie6.jpg [NC,L,R]
RewriteRule ^((MAIN_[cdm][^_]+|icon|logo|SpryMenuBarCorner)_.*)\.png$ /images/$1.gif [NC,L,R]
RewriteRule ^(bg_gradient_.*)\.png$ /images/$1.jpg [NC,L,R]
