title: Codeigniter: is it still safe to set sess_match_ip to FALSE
body: <p>I'm working on a website where visitors from some countries are facing a problem with the codeigniter caching system. the cache is deleted after a request or two. after deep investigation i turned sess_match_ip and sess_match_useragent to FALSE and everything is working fine now.</p>
  
  <p>Is it safe to keep those configs as FALSE ?</p>
  
  <p>Thanks </p>
