Cloudflare proxy support for ASP.NET Core
Cloudlfare is a popular service providing (among others) reverse proxy/CDN services. That means that the web server is hidden behind Cloudflare's servers and does not have direct access to client IP address.
ASP.NET Core has a solution for this: the Forwarded Headers Middleware, which can read X-Forwarded-For
and similar headers and set HttpContext.Connection.RemoteIpAddress
property accordingly.
For these two to work together, one needs to set properly IP ranges of known networks, as published by Cloudflare. This library automates this process, by downloading list of IPv4 and IPv6 ranges and applying them.
Basic usage
First, install the Altairis.Services.Cloudflare
package.
Then, in your Program.cs
, call the UseCloudflare
method. This is the minimal sample application:
using Altairis.Services.Cloudflare;
var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();
// Configure to use Cloudflare proxy
app.UseCloudflare();
// Show assumed client IP
app.MapGet("/", (HttpContext context) => context.Connection?.RemoteIpAddress?.ToString());
// Run application
app.Run();
Advanced usage
You may use the static method CloudflareForwardedHeadersConfigurator.GetForwardedHeadersOptions
to get ForwardedHeadersOptions
class configured for CloudFlare and then configure the Forwarded Headers Middleware yourself.
