htaccess mobile redirect - .htaccess

Question

I have a desktop and mobile site - I have the following in my htaccess file which means on a mobile site it gets stuck in a loop trying to redirect back to the main root of the domain and back to the mobile site folder on the domain.
How can I stop this happening?

# Now redirect to the mobile site
RewriteRule ^ http://www.domain.co.uk/m [R,L]

Answer 1

There may be a better way but i took out the look ups for if the site is a mobile and put
#mobile redirect
RewriteCond %{REQUEST_URI} !^/m/.*$
RewriteCond %{HTTP_USER_AGENT} "android|blackberry|ipad|iphone|ipod|iemobile|opera|mobile|palmos|webos|googlebot-mobile" [NC]
RewriteRule ^(.*)$ /m/$1 [R=301,L]
Which has worked nicely.
