Wordpress re-enabling Redis Nginx level caching for mobile devices ?

To re-enable mobile cache you need to edit the include files for your selected wordpress caching include file

where ${vhostname} is your domain.com name

for keycdn cache enabler would be at /usr/local/nginx/conf/wpincludes/${vhostname}/wpcacheenabler_${vhostname}.conf so uncomment and add hash # in front of 2nd line and restart nginx + php-fpm so looks like below

Code (Text):

    # exclude mobile devices from cache enabler caching
    #if ($cmwpcache_device = mobile) { set $cache_uri 'nullcache'; }

for redis nginx level cache would be at /usr/local/nginx/conf/wpincludes/${vhostname}/rediscache_${vhostname}.conf so uncomment and add hash # in front of 2nd line and restart nginx + php-fpm so looks like below

Code (Text):

# exclude mobile devices from redis caching
#if ($redis_device = mobile) { set $skip_cache 1; }

for wp super cache there doesn't seem to be a mobile cache setup configured

then restart Nginx and PHP services
