Headers in Prerendering

Headers in Prerendering allow you to tailor the prerendering process to your specific requirements. You can exercise control over prerendering behavior with customizable passthrough, allowlist, and caching control headers. You can specify which pages should be prerendered based on unique attributes, allowing you to focus on a specific user base.

📄️ Pass-through Headers

Pass-through headers facilitate greater flexibility and control during the prerendering process. These headers act as conduits for transmitting specific instructions or preferences from web crawlers to the prerendering service.

📄️ Caching Control Headers

Caching control headers offer a layer of control over the caching behavior in Prerendering, particularly when different versions of a web page need to be served to bots. These headers determine how and when the rendered pages are stored in the cache, which impacts how bots interact with your site.

📄️ Allowlist-Based Header Values

Allowlist-based header values help confirm the legitimacy of requests coming from the Prerendering service to your origin server, ensuring both security and integrity.
