A crash in H2 was reported in issue All candidate locations along this path have been secured against this risk, but the code should really evolve to stop depending on CS anymore. This fix must be backported to 1. Thank you for your quick response, testing in production.

Possibly that we should drain the whole data until the client aborts seeing it gets its respones. At least we must not freeze nor send a code suggesting the request is retryable. It can relatively easily be adapted to 1. It's worth noting that this situation matches none of the conditions described by the comments there.

Also it doesn't make sense to proceed again with HLOC in shutw : it's supposed to have been done already. Only for shutr it makes sense. And at the same time the explicit tests for this state should be removed. Note that 1. It seems again that part of the problem here is that "error" is a competing state for our streams and that instead we should let the state always match the protocol state machine and have a separate error flag which could be combined with these.

It goes a bit further than this. Can we decide that a closed connection finishes transitions just like an ES bit would do? Doesn't seem so. Skip to content.

Since Spring usually picks very reasonable defaults we started of with the default Tomcat implementation note that you need at least version 1. I saw I lot of plain text non-TLS support, but always thought that was a bad idea.

Plain text or clear text, hence the c in h2c is not supported. At first this might sound strange, but this helps the adoption of https. H2c was developed for the communication between web server and proxy. Sending HTTP over plain text is usually a bad idea because someone with a packet sniffer can easily listen in on your connection for example on unprotected wifi.

So why is h2 support so limited in Java? After watching a talk by Simone Bordet things made a lot more sense. After watching the talk, HAProxy seemed the way to go. I still was very hesitant to use it since the logo and web site look like they were never updated since Google was launched that was in But looks can be deceiving. To setup HAProxy the Jetty documentation is excellent.

Just follow the instructions until the paragraph of the Jetty setup. To setup spring-boot use the github project by Toshiaki Maki. Exclude all ssl entries from the application.

I also tested the configuration with Tomcat and that works fine. Make sure you use version 1. So kudos to Undertow and Tomcat for making it so easy. Now HAProxy has to be started. On mac os X the command is : sudo haproxy -f haproxy.

When this is not possible pick a port higher than The best thing to do is test your setup with wireshark. I only ran a very rudimentary test, but with significant results. Setting up SSL takes about 3. This is a factor 8. I restarted the server 10 times so I got a fresh connection and looked in the Chrome web inspector to see how long the SSL handshake took.

In the screenshot below the handshake took 3. Unfortunately it is replaced by HAProxy and is it still possible to capture packets in plain text, which is a small security risk.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I have tried the following configuration using this tutorial :. I get the following error message:. I suspect this is because HAProxy is expecting h2 data instead of h2c in the response. Any suggestion on what I need to change in the HAProxy configuration to support incoming h2c requests?

It is possible to proxy incoming requests in tcp mode providing your back end server supports h2c. HAProxy 1. To be honest h2c support in the front end is often of limited use since browsers do not support it and since it would require either an upgrade step or an assumption the server supported it neither of which is idealunlike h2 which can be negotiated as part of the TLS negotiation with no extra round trips or assumptions.

Is there a particular reason you want h2c support in the front end as there may be better ways of achieving what you want. Based on the discussion in the HAproxy channel, it is possible to proxy h2c requests using the proto h2 setting on bind.

Barry Pollard Barry Pollard I'm building a proxy for web services where clients may choose to speak h2c or h2 and HAProxy does the necessary SSL termination before sending h2c traffic to the backend. Yes curl does that because of the options you passed to it, but other clients may not do that. However the reason browsers only support h2 is because they saw problems deploying h2c on the public internet. So if your web service will likely see same issues.

The solution works nicely! Mar 27 at Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password. Post as a guest Name. Email Required, but never shown.
