Variable Edge Caching (Requires Accelerated Domains)
We’ve introduced support for Vary Headers Caching, unlocking smarter edge caching with Accelerated Domains. It allows cache separation at the edge based on specific request headers, enabling personalized content delivery without sacrificing cache performance. Instead of serving one generic cached version to every visitor, your site can now cache and deliver the right version instantly — without bypassing cache or adding backend complexity.
This means:
Personalized experiences at full edge speed
Higher cache hit ratios
No performance trade-offs
New Cache Variation Options
Available under: Servebolt Optimizer → Cache → Cache Settings
(Visible when Accelerated Domains is enabled)
You can now vary cache based on:
Device (User-Agent)
Automatically separates cache for Mobile, Tablet, and Desktop visitors.
Browser Language (Accept-Language)
Serves the correct language version based on the visitor’s primary browser setting.
Visitor Country (X-Origin-Country)
Enables country-specific content, pricing, or campaigns — fully cached at the edge.
These variations can be enabled individually or combined, depending on your site’s needs.
New: Purge PHP OPcache Button
Added a dedicated “Purge PHP OPcache” button directly in the WordPress admin.
This allows you to clear PHP OPcache instantly without SSH access or manual intervention — making deployments and troubleshooting faster and easier.
