Http-response add-header alt-svc 'h3=":1443" ma=60' if Īs such, compatible browsers are free to try to connect there or not. The main process constantly checks the QUIC one, and when it's seen as operational, it appends an Alt-Svc header that indicates the client that an HTTP/3 implementation is available on port 1443, and that this announce is valid for a short time (we'll leave it to one minute only so that issues can resolve quickly, but for now it's only 10s so that quick tests cause no harm): The range of possible issues would likely be frozen transfers and truncated responses, but these should not happen.įrom a technical point, the way it's done is by having a separate haproxy process listening to QUIC on UDP port 1443, and forwarding HTTP requests to the existing process. Be prepared to possibly observe a few occasional hiccups when visiting the site (and if so, please do complain to us). A few attempts were made and already revealed issues so for now it's disabled again. Thus the idea emerged, in order to continue to make progress on this front, to start to deploy QUIC on so that interoperability issues with browsers and real-world traffic can be spotted. While a few months ago we were counting the number of red boxes on the interop tests at to figure what to work on as a top priority, now we're rather counting the number of tests that report a full-green state, and haproxy is now on par with other servers in these tests. One front that made impressive progress over the last few months is QUIC.

And the star of this release is undoubtly the long-awaited support for the QUIC protocol! The full details are detailed here in the announce. It further improves reliability, and focused on making future contributions easier by simplifying some of the internals, and completing the native HTTP client, allowing easier interactions with external services.
HAProxy 2.6 is now the latest long-term supported release. Remember, you have one month and it's counting. If you have no idea yet, think about some great things or tricks you've achieved using HAProxy, or all the stuff tha made your friends tell you "you should really blog about it". It doesn't ask much, just your contact and a quick abstract. There's a simplified form to fill to propose a talk. Better not wait too much if you already have an idea in mind. The Call for Papers is now open and ends on September 5th, just after vacation. This year, HAProx圜onf 2022 will be held physically so that we can meet in person, just as we did in 2019! It will be held in Paris from November 8th to 9th. June, 16th, 2022 : HAProx圜onf: Call for Papers Please see the announnce for more details and/or consult the HAProxyTech blog article for more details. 2.7 provides traffic shaping, many QUIC improvements, eases the switch to alternate SSL libraries, and improves user experience with everything related to troubleshooting and issue reporting. HAProxy 2.7.0 is now released and available for download, opening the way to 2.8-dev.

Please make sure to update either to your latest distro package or to latest version It affects all currently supported branches, all the details are here on the mailing list announce. We've been notified of a vulnerability in HAProxy that can be exploited to build some request smuggling attacks.
