Only cache certain subdirectory

add_action( 'template_redirect', 'check_product_category_and_set_variable' );


function check_product_category_and_set_variable() {
	
    if (strpos($_SERVER['REQUEST_URI'], "xxx") === false){
        do_action( 'litespeed_control_set_nocache', 'no-cache some page' );
    }
    else {
        do_action( 'litespeed_control_set_cacheable', 'cache for some page ');
    }
}

please replace the xxx to your targeted URI , partial match also works , add this code to your theme’s functions.php

this is amazing! Thank you for your reply. Ok, so in this case, do I need to include a wildcard, and if in the future I wanted to include multiple directories, would I separate with a comma?

so for example, here I’m trying to cache only:

https://howtofightnow.com/course/*

so:

add_action( ‘template_redirect’, ‘check_product_category_and_set_variable’ ); function check_product_category_and_set_variable() { if (strpos($_SERVER[‘REQUEST_URI’], “/course/*”) === false){ do_action( ‘litespeed_control_set_nocache’, ‘no-cache some page’ ); } else { do_action( ‘litespeed_control_set_cacheable’, ‘cache for some page ‘); } }

If I wanted to add a directory, how would I do that? Comma separate like “/course/*,/videos/*”

thank you again for your time and help!

no , it needs to be /course/ , but this is partial match and doesn’t matter the position , as /course/somethign/ and /something/course/ both match , to make it exact match as beginning of URI is bit of more complicated though

if you have another target, then you can try

add_action( 'template_redirect', 'custom_caching_rule' );


function custom_caching_rule() {
	
    if (strpos($_SERVER['REQUEST_URI'], "xxx") === false && strpos($_SERVER['REQUEST_URI'], "yyy") === false){
        do_action( 'litespeed_control_set_nocache', 'no-cache some page' );
    }
    else {
        do_action( 'litespeed_control_set_cacheable', 'cache for some page ');
    }
}

Incredible! Thank you so much.

Is there any way to confirm if this is working as expected?

you can check http response header on pages, if you see x-litespeed-cache-control: no-cache means this page is not cached

otherwise you will see x-litespeed-cache: miss/hit , that means this page is cacheable

I must have done something wrong. I added:

add_action( ‘template_redirect’, ‘custom_caching_rule’ );

function custom_caching_rule() {

if (strpos($_SERVER['REQUEST_URI'], "/course/") === false){
    do_action( 'litespeed_control_set_nocache', 'no-cache some page' );
}
else {
    do_action( 'litespeed_control_set_cacheable', 'cache for some page ');
}

}

…but I’m getting this under cache on the following page:

https://howtofightnow.com/course/the-head-movement-training-program/day-3/reading-your-opponent/

(This definitely has /course/ in it)

I’m getting: https://capture.dropbox.com/WgBCpEuvXT1Rs7se

“Access-Control-Allow-Origin:

Alt-Svc:

h3=”:443″; ma=86400

Cache-Control:

no-cache, must-revalidate, max-age=0, no-store, private”

…so I’m guessing that this did not work?

THank you again for your time. Sorry I’m not great at this.

no , the cache-control is browser cache, nothing to do with our cache system

but it seems you are not using LiteSpeed webserver, in this case, our plugin won’t be able to cache any pages at all.

Ok, currently I’m running apache on the front end, and nginx on the backend on a plesk server. Do you provide set up for Litespeed webserver as a service?

I’m on an Ec2 instance as well.

Just want to make this whole thing as fast as possible. Not sure if my wordpress application is compatible though.

How could I find out?

in your case, without actual LSWS, you can check response header as well though

for cacheable page , you should see x-litespeed-tag: xxxxx

for no-cachebale page, you should see x-litespeed-cache-control: no-cache , or not seeing x-litespeed-tag at all

installation on Plesk should be simple and easy , we have document and video guide if you want to do it yourself, and of course, we also have installation service as well if you want ??

Ok, I do see:

X-Litespeed-Tag:

d88_tag_priv,public:d88_HTTP.200

Here’s a screenshot: https://capture.dropbox.com/vOPPt6aCiorw6KMp

Does this mean that the page is being cached effectively?

Thank you again for your time and help, and Merry Christmas!

yes that means this page is cacheable , but currently it is not actually cached as I have explained before due to webserver.

Merry Christmas ??

Ok, do you guys provide paid set up services for litespeed web server?

yes of course, please check this page

Ok, so before I move forward with this, I’m just curious if litespeed web server is something that will typically run in conjuction with both apache and nginx. Right now, apache is responsible for most of the ‘front end’ stuff on my site, including php, but nginx runs some other functions. I believe that htis is due to the server being a plesk server.

Will litespeed web server replace apache or nginx, or would it work in conjunction with them somehow?

Also, this seems like it would be a major adjustment on my server. Is there any way to measure the actual benefit that I would receive on the page that I shared with you?

If there is a way to show a performance increase, I would definitely move forward with the set up.

Thank you!
