Geolocation Webshop

[cyrix2000]

Hi,
I have a webshop which is selling internationally, in different currencies (USD, EUR and GBP) and with different VAT rates (EU country based, Norway and UK). I'm using Litespeed Webserver (incl. Wordpress plugin) together with quic.cloud as CDN. I have setup different caches for each VAT/currency combination in the webshop via rewrite rules in the .htaccess file (see below).

My problem is, that customers accessing the website without being logged in, don't see the correct currency/VAT combination (they are seeing a cached version of the site, but not from the cache "appropriate" for them).

I'm wondering what I may have misconfigured in Litespeed Cache/quic.cloud/htaccess, which is causing this problem.

Here the geolocation cache related .htaccess rules (geoloaction is activated on the Litespeed webserver):

If you temporarily deactivate quic.cloud, you will most likely be able to identify the cause.

 

[cyrix2000]

How would I identify it, after I disabled quic.cloud?

 

[serpent_driver]

If you temporarily deactivate quic.cloud and the custom cache vary works, then you know that quic.cloud cannot be used for your needs. The probability is about 100% that QC does not support your cache vary.

 

[serpent_driver]

Do you use any plugin for the IP-dependent display of the respective prices?

 

[cyrix2000]

Yes, I'm using the Aelia Currency Switcher for the prices.

Are you aware of a CDN which supports caching based on geolocation?

 

[serpent_driver]

The problem is the lack of synchronization between the origin host and the CDN node, or the availability of Cache Vary. Quic.cloud was developed specifically for the LiteSpeed Cache Plugin and LScache, but QC does not (yet) support custom cache vary. Also, you can't warm up the cache with QC. All other CDN providers are excluded from the outset because they offer caching but do not vary caches. You therefore only have 3 options:

1. Skip QC and use Anycast instead. This would have several advantages without any significant disadvantages.
2. Use QC, but solve the pricing problem with an AJAX solution so there is no need for cache vary.
3. Avoid displaying different prices depending on the IP.
