   define('SERVER_HOST',"your_hostname")
   

1. Using Redux cache
   • At myamiweb/config.php
     

     define('USE_REDUX_CACHE',true)
     

   • Turn it on or off in redux/pipeline.py
   • Input the desired disk_cache_path, disk_cache_size, and mem_cache_size in the next few lines
   • Create the disk_cache_path before running redux if cache will be used
     

     mkdir /tmp/redux
     chmod 777 /tmp/redux
