Browser cache not working

hmmmmmm, could you disable all other plugins to try ? I just installed a WP 4.8.4 with LSCWP 1.8.3 , all min/*.css are properly set cache header

Hello,

First of all i do not see litespeed cache to hit. Please check plugin settings and server settings.

I was digging in the documentation and just discoverede that openlitespeed does not support htaccess.

Is this correct?

If so, I should add all the htaccess content on rewrite section of admin panel?

Mmm…I’ve solved the htaccess problem by adding

rewriteFile /usr/local/lsws/prestitiinpdap.it/html/.htaccess

in rewrite section. Now X-LiteSpeed-Cache: hit is correctly sent.

The question now is:

Should I add Header set Cache-Control "max-age=31536000, public" to my files? Or is it suppesed to be handled by litespeed cache?

Here’s my htaccess file:

# BEGIN LSCACHE

And here’s my cache module config:

enableCache 0
enablePrivateCache 0
checkPublicCache 1
checkPrivateCache 1
qsCache 1
reqCookieCache 1
ignoreReqCacheCtrl 1
ignoreRespCacheCtrl 0
respCookieCache 1
expireInSeconds 3600
privateExpireInSeconds 3600
maxStaleAge 200
maxCacheObjSize 10000000
storagepath cachedata
noCacheDomain
noCacheUrl
no-vary 0
addEtag 0

Further informations: if you go on https://www.prestitiinpdap.it/mutui-inpdap/ you see that image have cache-control but it’s not hit by litespeed cache.

However css and js doesn’t have any expires header.

Seems a bug on openlitespeed. I’d like to have help on this. I can create a user and give access to check if it’s my misunderstanding of server settings or a serious bug.

Hi, @tropicalista

Thank you for all of the updates and details you’ve sent so far.

Should I add Header set Cache-Control “max-age=31536000, public” to my files? Or is it suppesed to be handled by litespeed cache?

Once you enable Browser Cache (at the bottom of LiteSpeed Cache > Settings > Cache), the headers will be taken care of for you. You don’t need to do anything else.

Further informations: if you go on https://www.prestitiinpdap.it/mutui-inpdap/ you see that image have cache-control but it’s not hit by litespeed cache.

I visited the link and I do see x-litespeed-cache:hit. If you don’t, it’s possible you are logged in and you have Cache Logged-In Users set to OFF. Try viewing your page from an incognito window and see if it behaves the way you would like it to behave.

Let us know if things are still not right from the incognito window, and what, specifically, is still not working.

I just noticed you’re getting some help in our main forum, so I’ll go ahead and close this post to avoid duplicate effort.
