# HTTP3 (and QUIC)

and libcurl.

## QUIC libraries
|
||
|
|
|
||
|
|
QUIC libraries we're experiementing with:
|
||
|
|
|
||
|
|
[ngtcp2](https://github.com/ngtcp2/ngtcp2)
|
||
|
|
|
||
|
|
[quiche](https://github.com/cloudflare/quiche)
|
||
|
|
|
||
|
|
## Experimental!
|
||
|
|
|
||
|
|
HTTP/3 and QUIC support in curl is not yet working and this is early days.
|
||
|
|
Consider all QUIC and HTTP/3 code to be **EXPERIMENTAL** until further notice.
|
||
|
|
|
||
|
|
curl does not have HTTP/3 support (yet).
|
||
|
|
|
||
|
|
The bleeding edge QUIC work is done in the dedicated
|
||
|
|
[QUIC](https://github.com/curl/curl/tree/QUIC) branch, but the plan is to
|
||
|
|
merge as often as possible from there to master. All QUIC related code will
|
||
|
|
remain being build-time conditionally enabled.
|
||
|
|
|
||
|
|
# ngtcp2 version
|
||
|
|
|
||
|
|
## Build
|
||
|
|
|
||
|
|
1. clone ngtcp2 from git (the draft-17 branch)
|
||
|
|
2. build and install ngtcp2's custom OpenSSL version (the quic-draft-17 branch)
|
||
|
|
3. build and install ngtcp2 according to its instructions
|
||
|
|
4. configure curl with ngtcp2 support: `./configure --with-ngtcp2=<install prefix>`
|
||
|
|
5. build curl "normally"
|
||
|
|
|
||
|
|
## Running
|
||
|
|
|
||
|
|
Make sure the custom OpenSSL library is the one used at run-time, as otherwise
|
||
|
|
you'll just get ld.so linker errors.
|
||
|
|
|
||
|
|
## Invoke from command line
|
||
|
|
|
||
|
|
curl --http3-direct https://nghttp2.org:8443/
|
||
|
|
|
||
|
|
# quiche version
|
||
|
|
|
||
|
|
## build
|
||
|
|
|
||
|
|
Build BoringSSL (it needs to be built manually so it can be reused with curl):
|
||
|
|
|
||
|
|
% mkdir -p quiche/deps/boringssl/build
|
||
|
|
% cd quiche/deps/boringssl/build
|
||
|
|
% cmake -DCMAKE_POSITION_INDEPENDENT_CODE=on ..
|
||
|
|
% make -j`nproc`
|
||
|
|
% cd ..
|
||
|
|
% mkdir .openssl/lib -p
|
||
|
|
% cp build/crypto/libcrypto.a build/ssl/libssl.a .openssl/lib
|
||
|
|
% ln -s $PWD/include .openssl
|
||
|
|
|
||
|
|
Build quiche:
|
||
|
|
|
||
|
|
% cd ../..
|
||
|
|
% QUICHE_BSSL_PATH=$PWD/deps/boringssl cargo build --release
|
||
|
|
|
||
|
|
Clone and build curl:
|
||
|
|
|
||
|
|
% cd ..
|
||
|
|
% git clone https://github.com/curl/curl
|
||
|
|
% ./buildconf
|
||
|
|
% ./configure --with-ssl=$PWD/../quiche/deps/boringssl/.openssl --with-quiche=$PWD/../quiche --enable-debug
|
||
|
|
% make -j`nproc`
|
||
|
|
|
||
|
|
## Running
|
||
|
|
|
||
|
|
Make an HTTP/1.1 request to a QUIC server:
|
||
|
|
|
||
|
|
% src/curl --http3-direct https://cloudflare-quic.com/
