Question

What s the payload limit of HTTP load balancer in GCP

Answer 1

Google Fronted process all request created to any Google product/service.

GFE is that the initial communication layer that controls all requests that get in and out the complete google network no matter the product.

The maximum payload allowed as well as the header is around 16K, as such, total combined header length ought to be but maximum limit.

The requests which are bigger than 16K doesn't reach your application and are not logged in Stackdriver logging.
