LScache problem with Joomla site

[vahid07]

Hi,

my webserver was Apache+nginx and recently i changed it to OLS for increase websites page load.

for use of lscase i changed httpd-lscache.conf to this:

module cache {
ls_enabled          1

checkPrivateCache   1
checkPublicCache    1
maxCacheObjSize     10000000
maxStaleAge         200
qsCache             1
reqCookieCache      1
respCookieCache     1
ignoreReqCacheCtrl  1
ignoreRespCacheCtrl 0

enableCache         0
expireInSeconds     3600
enablePrivateCache  0
privateExpireInSeconds 3600

}

and install joomla plugin (and its enable with default) and insert this code in .htaccess of that:

<IfModule LiteSpeed>
CacheLookup on
</IfModule>

and the graceful restart the OLS. but i cant see lscache header in page and also result of https://check.lscache.io/ test is :LSCache is not supported

so whats the problem?!

** amazing issue is i installed wordpress in a new directory of my joomla site and then enable lscache form "directadmin LWS plugin" and it show lscache head !! result of https://check.lscache.io/ for it is :
LSCache is supported
LiteSpeed cache is a hit
