The very best LiteSpeed Cache Varies for OpenCart if Journal 3 and LSWS is used

serpent_driver · Aug 30, 2022

The previously recommended cache varies for LiteSpeed LScache and the cache plugin for OpenCart are no longer available because these cache varies were no longer sufficient for the current version of Journal 3. If you are looking for cache varies optimized specifically for OpenCart and Journal 3, you can get detailed information at https://www.cachecrawler.com/Downlo...iteSpeed-LScache-OpenCart-Extension::114.html about it.

1. isDesktop - not necessary, because this is default public cache
2. isTablet - also not necessary, because exist ismobile with _lscache_vary=device:mobile cookie for mobile and _lscache_vary=device:tablet for tablet.
3. only Safari 14 or greater support webp - WebP image format | Can I use... Support tables for HTML5, CSS3, etc
4. Journal 3 has own algorithm for detection
5. chrome-lighthouse is wrong!!!! keys , because bot are next UAs:

Code:

Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_6) AppleWebKit/537.36 (KHTML, like Gecko) HeadlessChrome/96.0.4664.45 Safari/537.36
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) HeadlessChrome/96.0.4664.45 Safari/537.36
Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) HeadlessChrome/96.0.4664.45 Safari/537.36

but when you start check by Lighthouse, it use:

Code:

Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4695.0 Safari/537.36 Chrome-Lighthouse
Mozilla/5.0 (Linux; Android 7.0; Moto G (4)) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4695.0 Mobile Safari/537.36 Chrome-Lighthouse

these UAs accept cookies and NOT bot!

6. wrong way use different rules for same vary

7. wrong way start rule from ! (NO)

right way - use _lscache_vary cookie:

PHP:

        if (($browsercheck=$this->checkBrowser()) && isset($this->lscache->setting['module_lscache_vary_safari']) && ($this->lscache->setting['module_lscache_vary_safari']=='1'))  {
            $vary['browser'] = $browsercheck;
        }



    protected function checkBrowser() {

        if ( isset($_SERVER['HTTP_USER_AGENT']) ) {
        if ( (stripos($_SERVER['HTTP_USER_AGENT'], 'OPR') !== FALSE) || (stripos($_SERVER['HTTP_USER_AGENT'], 'OPT') !== FALSE) || (stripos($_SERVER['HTTP_USER_AGENT'], 'Opera') !== FALSE) ) {
            //return 'opera';
            return 'chrome';
        }

        if ( (stripos($_SERVER['HTTP_USER_AGENT'], 'FxiOS') !== FALSE) || (stripos($_SERVER['HTTP_USER_AGENT'], 'Firefox') !== FALSE) ) {
            //return 'firefox';
            return 'chrome';
        }

        if ( (stripos($_SERVER['HTTP_USER_AGENT'], 'Edg') !== FALSE) ) {
            //return 'edge';
            return 'chrome';
        }

        if ( (stripos($_SERVER['HTTP_USER_AGENT'], 'YaBrowser') !== FALSE) ) {
            //return 'yandex';
            return 'chrome';
        }

        //if ( (stripos($_SERVER['HTTP_USER_AGENT'], 'Lighthouse') !== FALSE) || (stripos($_SERVER['HTTP_USER_AGENT'], 'Headless') !== FALSE) ) {
        //if ( (stripos($_SERVER['HTTP_USER_AGENT'], 'Lighthouse') !== FALSE) ) {
        //    return 'lighthouse';
        //}

        if ( (stripos($_SERVER['HTTP_USER_AGENT'], 'CriOS') !== FALSE) || (stripos($_SERVER['HTTP_USER_AGENT'], 'Chrome') !== FALSE) ) {
            return 'chrome';
        }

        if ( (stripos($_SERVER['HTTP_USER_AGENT'], 'Safari') !== FALSE) ) {
            return 'safari';
        }

        if ( (stripos($_SERVER['HTTP_USER_AGENT'], 'Instagram') !== FALSE) ) {
            //return 'instagram';
            return 'safari';
        }
        return 'unknown';
        }
        return FALSE;
     }

Sorry, it works.

works, but NOT very best!!!

for example:

Code:

RewriteCond %{HTTP:sec-ch-ua-mobile} ^\?1$
RewriteCond %{HTTP:sec-ch-ua-platform} "^android$" [NC]
RewriteCond %{HTTP_USER_AGENT} "!bot|windows|linux|cros|chrome-lighthouse" [NC]
RewriteRule .* - [E=Cache-Control:vary=ismobile]

#1
RewriteCond %{HTTP_USER_AGENT} "android|mobile" [NC]
RewriteCond %{HTTP_USER_AGENT} "!bot|safari|iphone|ipad|chrome-lighthouse" [NC]
RewriteRule .* - [E=Cache-Control:vary=ismobile]

this is SAME rules!!!!!
if android is present in UA - this mobile or tablet.
why you use SAME rules twice?

if android present in UA - NO!!!!!!! iphone or ipad - impossible!!!!!
if android present in UA - NO!!!!! windows - impossible!!!!!

but this is you way

serpent_driver · Aug 30, 2022

You can't say that because you would have to test it practically, which you don't have. I tested it for several days.

AndreyPopov · Aug 30, 2022

serpent_driver said:

and what?

I not say - "they are not work".
I say - this is wrong way and many rules NOT necessary!

ONE rule!!!!! replace four you "best" rules

Apache config:

RewriteCond %{HTTP_USER_AGENT} Android [NC]
RewriteCond %{HTTP_USER_AGENT} !Bot [NC]
RewriteRule .* - [E=Cache-Control:vary=ismobile]

serpent_driver · Aug 30, 2022

AndreyPopov said:

Yes and no. The point is that I want to include every naturally user, not bots or users that simulate a natural user. I have information for this you don't have.

AndreyPopov said:

If I make a device detection I make it complete and don't exclude tablets.

AndreyPopov said:

Yes and what is your problem?
In contrast to your cache varies, mine work because I use them correctly and not just copy them from other sources, which then cannot work because the prerequisites for them are missing.

AndreyPopov said:

You post a request that has nothing to with Lighthouse. Yours only a headless request.

AndreyPopov · Aug 30, 2022

first: not need chrome-lighthouse - enough use only lighthouse
second: UA with chrome-lighthouse are NOT bot!
bots are NOT accept cookies

this is you way. but it is wrong and not in any place "best"

but this is your way

AndreyPopov · Aug 30, 2022

this rule:

Code:

RewriteCond %{HTTP_USER_AGENT} *Version/(\d{2}).*Safari [NC]
RewriteCond %1 <=13
RewriteCond %{HTTP_USER_AGENT} "!iphone|ipad" [NC]
RewriteCond %{HTTP_USER_AGENT} "!bot|windows|linux|cros|chrome|mobile|android|chrome-lighthouse" [NC]
RewriteRule .* - [E=Cache-Control:vary=isNoWebpSafari]

for what? for old Mac and MacBook? or for what?

serpent_driver · Aug 30, 2022

Lighthouse with or without chrome doesn't matter. Don't nag about unessential space here.
The lighthouse cache vary is only for guys who wants to see the very best result if they manually check their page at Pagespeed. For practical use this vary is obsolete. The same with bots. Bots should not get cached pages.

As long as you use wrong and not working cache varies you are not allowed to criticize!

This is for Safari desktop users that have OS version <13 because version <13 don't support webp images

AndreyPopov · Aug 30, 2022

serpent_driver said:

why than you need isBot vary? for what?

AndreyPopov · Aug 30, 2022

serpent_driver said:

you set NO iphone and NO ipad
you set NO windows and NO linux

what users more can use Safari?

only Mac and MacBook that use MacOS
Safari 14.0 – 15.6 has full support of WebP, but requires macOS 11 Big Sur or later.

AndreyPopov said:

A question that you should actually be able to answer. In my opinion, bots shouldn't get any cached pages.

serpent_driver · Aug 30, 2022

AndreyPopov said:

This is for harden cache varies. Not really necessary, but it doesn't hurt to use it.

serpent_driver · Aug 30, 2022

Have you ever heard about sec-ch* headers?

AndreyPopov · Aug 30, 2022

serpent_driver said:

once again and again - lscache and Journal use UA for detection.
when lscache and Journal will use sec-ch headers for detection algorithm than ask me again.

AndreyPopov · Aug 30, 2022

UA detection doesn't matter if the result is the same without UA and without wrong detection. UAs can be faked, sec-ua* headers not.

serpent_driver · Aug 30, 2022

Again, you use wrong cache varies copied from other applications you don't have with OC.
