If your WooCommerce store serves customers worldwide and uses multi-currency plugins, you can optimize cache performance for international visitors by configuring Cache Warmup to recognize different currencies.
This ensures your international customers see the correct currency and experience faster loading times from their very first visit. This guide will show you how to set up multi-currency cache warmup using dynamic content cookies.
When This Feature Is Useful
This feature is essential for WooCommerce stores that serve customers in multiple countries and use multi-currency plugins to display localized pricing.
Without a multi-currency cache setup, your international customers may experience:
Visitors see wrong currency (e.g. USD instead of EUR/GBP/CAD)
Currency only switches after manual selection
Slower loading for international visitors
Cache misses requiring currency recalculation
Pricing confusion and potential cart abandonment
How Multi-Currency Cache Warmup Works
Cache Warmup can create separate cached versions of your pages for different currencies by:
Recognizing currency cookies - Identifies which currency a visitor should see
Using geolocation data - Matches IP addresses to appropriate currencies
Creating currency-specific cache - Stores optimized versions for each currency
Serving localized content - Delivers the right currency version instantly
How to Set Up Multi-Currency Cache Warmup
Step 1: Access Dynamic Content Cookies
Navigate to the NitroPack App >> Cache Settings >> Cache
Locate the Dynamic Content Cookies in the Cookies section.
Step 2: Add Your Currency Cookie
You need to manually add the cookie name that your multi-currency plugin uses. The cookie name varies depending on your plugin:
Supported Multi-Currency Plugin Cookies:
CURCY Multi-Currency: wmc_current_currency
Aelia Currency Switcher: aelia_cs_selected_currency
WooCommerce Multilingual (WCML): wcml_client_currency
Step 3: Configure Cookie Values
The cookie values should match the currencies you support in your store. Common currency codes include:
USD - US Dollar
EUR - Euro
GBP - British Pound
CAD - Canadian Dollar
AUD - Australian Dollar
JPY - Japanese Yen
All of the aforementioned plugins use the ISO 4217 standard, you can find a full list of the currencies here.
Configuration Example:
Cookie Name: wmc_current_currency
Values: USD,EUR,GBP,CAD
Step 4: Save and Test
Click Save Changes
Purge your existing cache by navigating to Cache Settings >> Cache >> Cache Reset:
Allow time for new cache versions to generate
Test from different locations or using VPN
What Happens After Setup
Once configured, your international customers will experience:
Faster loading times - Pages load quickly with the correct currency
Immediate currency display - No waiting for currency detection or switching
Reduced confusion - Clear, localized pricing reduces cart abandonment
Troubleshooting
If currencies still appear incorrect:
Verify the cookie name matches your plugin exactly
Check that all currency codes are properly formatted (use standard 3-letter codes)
Ensure your multi-currency plugin is active and configured
Clear cache and allow few minutes for regeneration
If cache isn't generating for all currencies:
Confirm cookie values match your store's supported currencies
Test currency switching on your site to verify cookies are set
Check that geolocation features are enabled in your currency plugin
Verify Dynamic Content Cookies are saved correctly
Finding Cookie Information:
Use browser developer tools (F12) → Application/Storage → Cookies
Switch currencies on your site and observe which cookies change
Check your multi-currency plugin's settings or documentation
Contact your plugin developer for specific cookie details
