DESCRIPTION

This cmdlet adds and configures the ASP.NET Core Forwarded Headers middleware for a Kestrun server. This middleware processes proxy-related headers such as X-Forwarded-For, X-Forwarded-Proto, X-Forwarded-Host, and X-Forwarded-Prefix to update the request’s Scheme, Host, and Remote IP address accordingly. This is essential when hosting behind reverse proxies or load balancers that modify these headers.

EXAMPLES

EXAMPLE 1

Add-KrForwardedHeader -XForwardedFor -XForwardedProto -KnownProxies $proxyIps Adds Forwarded Headers middleware to the current Kestrun server, enabling processing of X-Forwarded-For and X-Forwarded-Proto headers, and trusting the specified proxy IP addresses.
