 # Cloudflare Error Page Generator
 
-📢 **Update (2025/12/09)**: All icons used in the error page have been fully redrawn as vector assets. These icons along with the stylesheet are also inlined into a single file of the error page, eliminating any need of hosting additional resources and ensuring better experience for you and your end users.

 ### How to show real user IP / Cloudflare Ray ID / data center location in the error page so that it looks more realistic?
 
-Ray ID and user IP field in the error page can be set by `ray_id` and `client_ip` properties in the `params` argument passed to the render function. The real Cloudflare Ray ID and the data center location of current request can be extracted from the `Cf-Ray` request header (e.g. `Cf-Ray: 230b030023ae2822-SJC`). Detailed description of this header can be found in [Cloudflare documentation](https://developers.cloudflare.com/fundamentals/reference/http-headers/#cf-ray (https://developers.cloudflare.com/fundamentals/reference/http-headers/#cf-ray)).
