LiteSpeed Crawler: Cookie Notice – Question

Hi,

1) crawler will act like a robot , which means if they see some kind of cookie banner , it won’t click “accept” or “reject” , but then leave the page

2) only if you have cookie vary rule

best regards,

Hi @qtwrk
The site’s using the Plugin GDPR Cookie Consent
https://www.ads-software.com/plugins/cookie-law-info/

The Cookie following cookies gets pre-set from this plugin on a pageview:

cookielawinfo-checkbox-non-necessary
cookielawinfo-checkbox-necessary

This cookie will be set after accepting the Cookie Consent:

CookieLawInfoConsent
viewed_cookie_policy

1. So to vary the cookie and cache different sites “states” based on cookies it would be like this inside the .htaccess file, right?:

<IfModule LiteSpeed>
RewriteEngine On
RewriteRule .* - [E=CookieLawInfoConsent]
RewriteRule .* - [E=viewed_cookie_policy]
</IfModule>

2. Is the order of the loaded Cookies important?
3. Can I shorten the cookie string like this to eliminate a line (or what does the comma do)?
RewriteRule .* - [E=CookieLawInfoConsent,viewed_cookie_policy]

1) yes , but use one of them should be enough , no need to do both , and make sure you put it at top of your .htaccess , and your rule is wrong , should be

RewriteRule .* - [E=Cache-Vary:viewed_cookie_policy]

2) yes , but not in your case , you just need to make sure it is on top of your .htaccess

3) no

Based on the questions above:

If I vary a cookie
1. Is the rule for the cookie nane case-sensitive? like
RewriteRule .* - [E=Cache-Vary:CookieLawInfoConsent]
or
RewriteRule .* - [E=Cache-Vary:cookielawinfoconsent]
2. Is there a way to visually “see” and/or check the results of a vary rule like a screenshot of a page?
3. What does the comma do? I saw it here: https://github.com/WpSpeedDoctor/litespeed-cookie-based-caching/blob/main/htaccess.txt (line 23)
is it like AND / OR / XOR?

1） it’s case sensitive

2) you probably can not directly “see” it , but you can use http response header and server log to verify this

for example you access one page , with cookie set , make sure you see it gives you hit , then check same page , but this time on a private window without cookie set , you should see it gives you miss again

3) I don’t know what does it , never seen it before , if you need to vary multiple cookies , make multiple lines , like

RewriteRule .* - [E=Cache-Vary:something]
RewriteRule .* - [E=Cache-Vary:something_else]

Thanks again @qtwrk that you enlighten me with your wisdom ??

Let’s say I would create a one-for-all htaccess file with a collection of Cookie/Cache-Vary and there are cookies inside the htaccess that would never be used.
Would this have a negative impact on speed/stability, cache hits and/or would this result into errors?

The logic behind this is to safe time and redundant work to not scan every site moved to LiteSpeed for the corresponding cookie.

more rules there is , more time it takes to process all the rules

but unless you have hundreds of rules , otherwise the time impact should be negligible , we are talking about like few millisecond

if you add a vary rule on cookie that doesn’t really used/set , then all request will go to that vary as cookie not set , so it won’t impact the cache hit ratio

Okay, understood.
Thanks again @qtwrk ! ??

Regarding the “comma rule”, I found it inside the docs as well at the second example, but the rule
– is inside quotation marks
– is written lower case, like the word combination cache-var
– isn’t documented indepth what it does (like: “Only if a and b matches, than cache the page.” Or “If a OR b matches, then cache the page”…)
https://docs.litespeedtech.com/lscache/devguide/advanced/#rewrite-rules

Would you mind to ask your team about that?

An addon question regarding OLS and cache-vary:
In OpenLiteSpeed, is it enough to edit the .htaccess or do I have to edit the Headers as well?

1) that’s for multiple cookie names

2) thougth you meant the cookie name , that is case sensitive , but

RewriteRule .* - [E=cache-vary:xxx]

part is OK

3) RewriteRule .* - [E="cache-vary:xf_style_id,xf_language_id"]

this works , I just ran a quick test , though I have never tried this before myself, personally prefer to split them up for easier readability

no , it makes vary on multiple cookies

let’s say , you have a page /

and you set vary cookie as test1 and test2 , then

case 1) user accesses with no cookie , with get one cache , let’s call it cache copy A

case 2) user accesses with cookie test1=1 , this will get a different cache , let’s call it cache copy B

case 3) user accesses with cookie test1=2 , this will be cache copy C

case 4) cookie test2=1 , cache copy D

case 5) cookie test2=2 , copy E

case 6) cookie test1=1 and test2=1 , copy F

and so on

in previous post , imagine you put 3 cookie varies

imagine they are test1 , test2 and test3 , and you seem look for one-for-all solution , let’s say only test3 cookie is actual and real , then the vary case will be like test1 and test2 will always match/vary on empty value and only count the test3 cookie.

To sum it up:
1) The comma is for multiple cookies – clear, thanks! ?
2) Cookies like CookieLawInfoConsent are case sensitive so it’s NOT RewriteRule .* - [E=Cache-Vary:cookielawinfoconsent]
it is
RewriteRule .* - [E=Cache-Vary:CookieLawInfoConsent]

And:
RewriteRule .* - [E=cache-vary:xxx] can also be written like RewriteRule .* - [E=Cache-Vary:xxx] ?
3) The short RewriteRule .* - [E="cache-vary:xf_style_id,xf_language_id"]
is equal to / is technically the same like

RewriteRule .* - [E=cache-vary:xf_style_id]
RewriteRule .* - [E=cache-vary:xf_language_id]

Both rulesets create a different cashed page depending on the set cookie and the cookie value. ?

So far correct?

Question on top of the discussed above:

Can I ouput ONE cached page if two cookies are set?
For example:
I want to be extra sure about the cookies

CookieLawInfoConsent
viewed_cookie_policy

–> If BOTH cookies are set, then output ONE cached version
((These are just imagined rules, not real rules! – for those who came here from Google for copy and pasting stuff)) – so something like:
RewriteRule .* - [E="cache-vary:CookieLawInfoConsent + viewed_cookie_policy"]
or
RewriteRule .* - [E="cache-vary:CookieLawInfoConsent && viewed_cookie_policy"]

what header ? for caching , just need the rewrite rules

as long as the cookies value are same , it will output the same cached page

like I explained above

when you have 2 cookies , the value of either cookies changes , will generate a new vary
