Potential bug in lab "Web cache poisoning via HTTP/2 request tunnelling"

Jesús | Last updated: Apr 07, 2023 03:25PM UTC

Hi, I'm trying to resolve the lab "Web cache poisoning via HTTP/2 request tunnelling". For some reason the server returns the error 504. May you advice? https://snipboard.io/pGVzvB.jpg Cheers, Jesús

Hi Have you tried adding more padding to the request so the length of the tunnelled response exceeds the Content-Length of a normal GET / response?
