Re: [jetty-dev] Can jetty proxy servlet work with http2 correctly?

I don't see Jetty involved in this description, or in the stacktrace.

But here, go follow the netty (different project then us) bug for this - https://github.com/grpc/grpc-java/issues/7953

Hi Jetty-Dev@Eclipse,

I am currently working on a research and trying to connect a Jetty server with a grpc(base using netty). Currently having below error over the grace server.

grpc server1 -> Jetty (proxyservlet) -> grpc server2
java.lang.UnsupportedOperationException

After couple attempts of debugging over the custom proxy servlet, I found that the request after being copied in AbstractProxyServlet it will be http1 request. So I want to ask if the proxyServlet will turn an http2 to http1 by default ? Will this be the cause of metadata damage or to the header? I have httpclient using http2 which turns the request back to http2.

Please let me know if anyone could help with this. And if possible, do you have any working example that a jetty server could talking to grpc server.

Thank you,

Danielle
