Mobile Site Redirect Loop Issue

  • Hello ??
    My goal is to detect mobile devices and automatically redirect them from my site (cornellkpl.org) to my mobile site (m.cornellkpl.org).
    I got the redirect code from detectmobilebrowsers.com and added it to my .htaccess file, but I get an error: “This webpage has a redirect loop”.
    I am using the Bridge theme by Qode and don’t have any redirect or mobile-related plugins, if that makes a difference.
    The content of the .htaccess file is below:

    RewriteEngine On
RewriteBase /

    I am fairly new to WP, and would really appreciate any help you can give!
    Thank you so much.

    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]

# if the request is from any one of the above devices

RewriteRule .? https://m.mysite.com%{REQUEST_URI}  [L,R=302]

    Thank you again!
