Cloudflare Worker bot prerender routing

RenderShield on Cloudflare Workers keeps browser delivery unchanged while adding deterministic crawler HTML for selected routes.

Delivery model

• Humans: normal SPA response path
• Bots: prerendered static HTML path
• Visibility: x-rendershield response header on both paths

Observed header values:

• x-rendershield: bot-hit for routed bot traffic
• x-rendershield: pass-through for normal browser traffic

Worker route base setup

Configure rewrite bases for the routes you want bots to receive as static HTML:

• /docs
• /prerender
• /blog

This keeps crawler scope narrow and auditable.

Minimal deploy sequence

npx rendershield init
npx rendershield build
rendershield verify --prod https://yoursite.com/prerender/cloudflare

Then deploy the generated Worker and static assets to Cloudflare.
