I do not what happen.
It redirect every country to /collection now, even I purge litespeed and cdn cache,

maybe this enough?

RewriteCond %{HTTP:x-qc-country} CN
RewriteRule ^/?$ https://www.theryang.com/collection/ [R=301,L]

Well. It does not work now…..
I think I still need to set up.
How should I write this logical

if page URL is / , and qc country header is CN , then vary
otherwise other

in .htaccess?

If I only want to redirect my homepage to https://www.theryang.com/collection/.
Do you think follow codes is a better way?

RewriteEngine on
RewriteCond %{HTTP:x-qc-country} CN
RewriteCond %{HTTP_HOST} ^(?:www\.)?theryang\.com$ [NC] 
RewriteRule ^/?$ https://www.theryang.com/collection/ [R=301,L]

In this way, I do not need to care about the vary cache and use Geoip plugin.

Thank you. They work.

I think this may because this plugin use the css style from my theme and some elements become wired.
For example, the layout of wishlish table looks not aligned correctly in mobile vesrion . Some of the font size is too small and some are too large. Is there a more convenient approach I can customize them instead of modify css everytime?

Plus, if I use YITH account page plugin, I can see the wishlist in account page menu, but ‘open the wishlist’ button will link to this menu instead of a single wishlist page. If I do not use YITH account page plugin, I cannot see the wishlist tab in account page menu. Are they mutually exclusive?

OK. I will continue testing this in the future and discuss with you if it failed someday.

Yes. I understand what you mean. But the redirection still works for my website without vary cache. That’s why I say it superises me.

You can test this link theryang.com if you have CN proxy

If visitor is from CN, it will be redirected to /collection/ instead of home page.
As I tested, it works everytime even though I switch my vpn to CN/non-CN each visiting.

I use IP2Location Redirection plugin and I have checked there php code. They use $_SERVER[‘REMOTE_ADDR’] or $_SERVER[‘HTTP_X_FORWARDED_FOR’] to get the geo ip.
I will keep testing if my case will still work without vary cache.

Sorry I found nobody maintain this plugin anymore. What a pity.
I think it has the potential to be a great optimize tool.

OK. I resolve the problem and want to share at here as a archive for others.
https://www.domain.com will go to my CDN.
As I debug, I find the Quic.Cloud CDN only send node ip as REMOTE-ADDRESS to my server.

I vardump($SERVER) and found there is a field ‘HTTP_X_CLIENT_IP’ can provide real clinet ip.

Then I add these codes to the top of wp-config.php:

<?php
// Use X-Forwarded-For HTTP Header to Get Visitor’s Real IP Address

if ( isset( $_SERVER[‘HTTP_X_CLIENT_IP’] ) ) {
$http_x_headers = explode( ‘,’, $_SERVER[‘HTTP_X_CLIENT_IP’] );

$_SERVER[‘REMOTE_ADDR’] = $http_x_headers[0];
$_SERVER[‘HTTP_X_FORWARDED_FOR’] = $http_x_headers[0];
}`

OK. Please treat the first question as a request.

For second one, I found it’s because WP 5.5 build-in lazy-load. I disable that and the PSI does not notice me about that again.

For third one. I annotate the vary cache codes and superisely find that my ip-based redirect plugin still works when I switch visiting from CN and Other countries. Maybe litespeed does not cache the HTTP_X_CLIENT_IP hearder so that plugin can get correct ip each time?

Yes. This work. Which lazy-load is more efficient? WP or Litespeed?

One more question:
I set 2 vary caches for CN and Other in .heaccess, respectively.

RewriteEngine on
RewriteRule .* – [E=Cache-Control:vary=other]
#set default vary to other
RewriteCond %{HTTP:x-qc-country} CN
RewriteRule .* – [E=Cache-Control:vary=CN]

In fact, I only need to vary cache for my homepage to redirect. Which I only need to create one more cache instead of create CN cache for every page (which uses up my quato everyday). Could you tell me how to set up it?

$_SERVER['REMOTE_ADDR'] = $http_x_headers[0];
$_SERVER['HTTP_X_FORWARDED_FOR'] = $http_x_headers[0];
}

This plugin claims they can modify the elements in iframe.

But I have installed too many plugins. I am looking for a light solution.

Thank you @essaund, this works for me. I also find LQIP is too ugly and in my website it only shows 0.5ms which seems to be uneccessary. Transparent Responsive Placeholder is the best solution so far.
