<p>I have a k8s service defined as <code>type: LoadBalancer</code> which sets an external LB. Can I identify on application level that an incoming request is routed from the LoadBlancer?</p>

<p>Are there any guaranteed http headers? Can I define custom headers for that service that would be added to all incoming requests?</p>

<p>If your internal ingress is using nginx as an ingress controller you can <a href="https://stackoverflow.com/a/11973844/3833773">add a custom header</a> that will indicate that.</p>
