How AffLoc works perfectly with caching plugins.

Cache Compatibility

AffLoc is specifically designed to work with all caching plugins. Here’s why.

The Problem with Server-Side Geolocation

Many link localization plugins modify the HTML on the server — rendering different HTML for different countries. This completely breaks page caching because a cached page shows the same HTML to everyone.

AffLoc’s Approach: Client-Side Swap

AffLoc takes a different approach:

  1. Server renders a static HTML page with the default link. This HTML is identical for every visitor and can be fully cached.
  2. A small JavaScript file (~5KB) runs after page load.
  3. JavaScript detects the country (via cached localStorage or REST API call).
  4. JavaScript swaps the link href to the country-specific URL.

Because the HTML itself never changes, your caching plugin caches one version for everyone. The link swap happens instantly in the browser.

Tested Caching Plugins

  • WP Rocket
  • W3 Total Cache
  • LiteSpeed Cache
  • WP Super Cache
  • Autoptimize
  • Cloudflare APO

Performance Notes

  • The frontend script only loads on pages that contain the shortcode.
  • Country detection is cached in the browser for 24 hours.
  • After the first visit, link swapping is instantaneous with no API calls.
