Starting a new thread for this.
I got HTTP/3 working with haproxy. Everything seemed to be going great,
and then I noticed that logins on PHP apps were getting a 400 response
back. At first I thought it might be something in PHP, but I have now
eliminated PHP as the problem. I can demonstrate it with simple html.
Open the following link in Chrome or Firefox:
https://raspi2.elyograg.org/form.html
Hold shift while clicking the reload button. That will almost guarantee
that it's using HTTP/3. This is a simple html form that issues a POST
request. I grabbed it from the internet. When you click the button to
send the greeting, you'll get a 400 error if the request was made with
HTTP/3. If it's made with 1.1 or 2, it works properly. I tested this
with links and curl. I have been trying to build a curl binary that
does http3, so far without luck.
Two different browsers have the same problem, so I am currently
speculating that it's an issue with haproxy or apache. I think I can
install nginx without too much trouble ... I have almost no experience
with it, so I get to learn something new.
Thanks,
Shawn
