Similarly, if you wanted to redirect to a sub-folder instead of a sub-domain, do the following:

Working off of Kevin's great solution you can add this to the .htaccess file in your site's root directory:

    
        RewriteBase /
        RewriteEngine On

        # Check if mobile=1 is set and set cookie 'mobile' equal to 1
        RewriteCond %{QUERY_STRING} (^|&)mobile=1(&|$)
        RewriteRule ^ - [CO=mobile:1:%{HTTP_HOST}]

        # Check if mobile=0 is set and set cookie 'mobile' equal to 0
        RewriteCond %{QUERY_STRING} (^|&)mobile=0(&|$)
        RewriteRule ^ - [CO=mobile:0:%{HTTP_HOST}]

        # cookie can't be set and read in the same request so check
        RewriteCond %{QUERY_STRING} (^|&)mobile=0(&|$)
        RewriteRule ^ - [S=1]

        # Check if this looks like a mobile device
        RewriteCond %{HTTP:x-wap-profile} !^$ [OR]
        RewriteCond %{HTTP_USER_AGENT} "android|blackberry|ipad|iphone|ipod|iemobile|opera mobile|palmos|webos|googlebot-mobile" [NC,OR]
        RewriteCond %{HTTP:Profile}       !^$

        # Check if we're not already on the mobile site
        RewriteCond %{HTTP_HOST}          !^m\.
        # Check to make sure we haven't set the cookie before
        RewriteCond %{HTTP:Cookie}        !\mobile=0(;|$)
        # Now redirect to the mobile site
        RewriteRule ^ http://www.mysite.com/m/ [R]
    

Then, in the /m/ folder, add or create an .htaccess with the following:

    #Begin user agent loop fix

         RewriteEngine Off
         RewriteBase /

    #End user agent loop fix 

I know it's not a direct answer to the question, but somebody (like me) might stumble upon this question and wonder how that method would be accomplished as well.
