Hey guys,

Does anybody know when Apache httpd will have support for HTTP/3?

I know HTTP/3 is not completely out yet, but it would be nice to know.

Thanks.

At least the first step to achieve this can be done, I just compiled httpd-2.4.54 using openssl-3.0.5+quic on a Fedora 36 VM, so if that can be done it's the first step to create a mod_http3 with the other core modules.

Also while doing that, nghttp2 said it also supports http3.

I just hope somebody starts working on this soon, I was trying nginx-quic and it sucks, I rather using Apache httpd.

At least on the browser side, it looks promising https://caniuse.com/http3

You are welcome to create mod_http3. A good starting point is https://github.com/icing/mod_h2

I wish I had the knowledge to do so, but I don't, so I better leave it to the experts.

To stay on the subject nghttp3 is available to use without OpenSSL+Quic, using the QPACK instead.

More info here: https://nghttp2.org/nghttp3/

I just hope somebody takes the lead and start working on it so we can have it available.

I wonder if this s why nothing is being done to get httpd have availability for http3: https://cwiki.apache.org/confluence/display/TS/Presentations+-+2022?preview=%2F211885742%2F211885754%2FHTTP3-ats-summit-2020-fall.pdf

Aparently it's slower than http2, or so it showed with ATS.

Another setback for HTTP3, this is from OpenSSL when I asked them when openssl was going to have support for quic:

Quote:
Initial QUIC support will be available in OpenSSL 3.2. However this support is planned to be limited (client side only, single stream only) - not really useable for http3. 3.3 is likely to have more extensive support. 3.2 will be out some time later this year. No timeline for 3.3 yet.
