FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Cloudflare Trusted Proxies Bundle for Symfony (Real IP & Reverse Proxy Support)
A production-ready Symfony bundle for integrating Cloudflare with Symfony applications. It ensures correct real client IP detection, trusted proxy configuration, and forwarded headers handling when Symfony runs behind Cloudflare.
Why use Cloudflare with Symfony?
When running Symfony behind Cloudflare, incorrect proxy configuration often causes:
- Wrong client IP addresses (
Request::getClientIp()) - Broken HTTPS / scheme detection
- Invalid security and rate-limiting behavior
This bundle automatically configures Symfony trusted proxies using official Cloudflare IPv4 and IPv6 ranges and keeps them up to date.
Features
- Automatic IP Updates: Automatically fetches and updates official Cloudflare IPv4 and IPv6 ranges for Symfony trusted proxies.
- Caching: IP ranges are cached using Symfony Cache to avoid overhead on every request.
- Zero Configuration: Works out of the box with standard Symfony environment variables (
TRUSTED_PROXIES). - Flexible: Customizable headers, caching, and merging logic.
- Feature Toggle: Easily enable or disable the bundle via config or environment variables.
Installation
After installation, register the bundle in your config/bundles.php:
After installation, you can automatically publish the configuration file to your project:
Compatibility
- PHP 8.1+
- Symfony 6.x
- Symfony 7.x
- Symfony 8.x
- Cloudflare (Free, Pro, Business, Enterprise)
Configuration
Environment Variables
By default, the bundle will automatically merge Cloudflare IPs with any proxies defined in your standard Symfony environment variable:
If you prefer to use a custom variable name, you can change proxy_env in the configuration.
Usage
The bundle hooks into the kernel.request event with high priority (2000),
so it runs before the Security component.
Commands
You can manually reload or view the cached IP ranges:
[!TIP] While the bundle refreshes the cache automatically on request, it is recommended to set up a cron job to keep the cache warm:
