Session
In the past HTTP was just used for websites. Today many applications depend on APIs, using HTTP(S) as communication protocol as well. So, when troubleshooting there is a big change that you have to investigate HTTP traffic. With HTTP/2 and HTTP/3 becoming more popular that may require a different approach.
This session is not only about how to use Wireshark, but especially about understanding the protocol. What the HTTP status codes really mean, quirks of cookies, caching done the right way, compression and more.
