The product’s URL remains the same regardless which currency I use. Under Chrome inspection, I can see the product is showing a “Hit” status for page cache, when I switch to another currency, it is showing as “missing”? * The URL is the same, so why is the latter not cached? * Here is a sample product: * [https://www.marsnvenus.com/shop/sample-product-a-copy/](https://www.marsnvenus.com/shop/sample-product-a-copy/) Viewing 15 replies - 1 through 15 (of 24 total) 1 [2](https://wordpress.org/support/topic/cache-query-string-2/page/2/?output_format=md) [→](https://wordpress.org/support/topic/cache-query-string-2/page/2/?output_format=md) * Plugin Support [qtwrk](https://wordpress.org/support/users/qtwrk/) * (@qtwrk) * [1 year, 8 months ago](https://wordpress.org/support/topic/cache-query-string-2/#post-18014826) * because it needs to be this way , otherwise you will see the currency remains unchanged * like your default is USD , when you change to other like EUR or GBP or something, if it still get cache , you will still see USD instead of selected currency * so it sets a cookie to determine the currency and vary on the cache * by that saying , same URI , if cookie value is XXX , then it serve one cache , if cookie value is YYY then it serve another different cache , if cookie is ZZZ, then another cache. * Thread Starter [raymond621](https://wordpress.org/support/users/raymond621/) * (@raymond621) * [1 year, 8 months ago](https://wordpress.org/support/topic/cache-query-string-2/#post-18014873) * thank you for writing back. * It looks like the crawler is only cache the default currency.
