changed it to below seems to be working!

Apachebench test of vB 3.8.6 PL1 front page index.php with litespeed cache enabled resulted in a boost from 256.63 rps to 4,334 rps with litespeed cache! Showthread page boost from 183 rps to 22,695 rps. That's >16x times faster for index.php and >123x times faster for showthread page 
Litespeed cache looking very good for guest visitor caching at least 
vB 3.8.6 PL1 index.php page - no cache vs cached
- without litespeed cache = 256.63.68 rps
- with litespeed cache = 4,334.46 >16x times faster!
