sarayunhakim on "Mobile Site Redirect Loop Issue"

Thank you!

The code shared on that blog, for some reason, prevented my page from loading. I ended up finding similar code, shown below. It seems to be working now, but do you think this code will cause any problems?

# turn on rewrite engine
RewriteEngine on

# only detect smart phone devices if we are not on mobile site
# to prevent redirect looping
RewriteCond %{HTTP_HOST} !^m.mysite.com$

# a bunch of smart phone devices
RewriteCond %{HTTP_USER_AGENT} "sony|symbian|nokia|samsung|mobile" [NC,OR]
RewriteCond %{HTTP_USER_AGENT} "windows ce|epoc|opera|mini|nitro" [NC,OR]
RewriteCond %{HTTP_USER_AGENT} "j2me|midp-|cldc-|netfront|mot" [NC,OR]
RewriteCond %{HTTP_USER_AGENT} "up\.browser|up\.link|audiovox" [NC,OR]
RewriteCond %{HTTP_USER_AGENT} "mini|nitro|j2me|midp-|cldc"[NC,OR]

RewriteCond %{HTTP_USER_AGENT} "wap2\.|iPhone|android"[NC,OR]

# redirect google mobile bot
RewriteCond %{HTTP_USER_AGENT} "googlebot-mobile"[NC]

# if the request is from any one of the above devices
# redirect to mobile site
RewriteRule .? http://m.mysite.com%{REQUEST_URI}  [L,R=302]

Thank you again!
