Reverse proxying HTTP/2 from h2 to h2c

冷暖自知 提交于 2019-12-12 08:07:17
问题 We have a java web server which is able to serve content over h2c (HTTP/2 clear text) We would like to reverse proxy connections established using h2 (i.e. standard HTTP/2 over SSL) to the java server in h2c. Enabling HTTP/2 on nginx is simple enough and handling incoming h2 connections works fine. How do we tell nginx to proxy the connection using h2c rather than http/1.1 ? Note: a non-nginx solution may be acceptable server { listen 443 ssl http2 default_server; server_name localhost; ssl

HTTP/2.0 in browser: How does Browser cancel Server Push?

北战南征 提交于 2019-12-12 05:08:50
问题 I've read documentation of HTTP/2.0 and I know that it is possible to fully terminates the referenced stream by using the RST_STREAM frame. Here's (https://http2.github.io/http2-spec/)! How can I implement this feature in a web browser like Google Chrome or Firefox? 回答1: As a browser user or web app developer (HTTP/Javascript) you can't. There is no public API for this, or to interact with server push in general. The possibility to do this is probably implemented in the network stack of the

Nodejs gRPC error with { [Error] code: 14, metadata: Metadata { _internal_repr: {} } }

问题 I used gRPC In my application, but I got an error like this { [Error] code: 14, metadata: Metadata { _internal_repr: {} } }, I can't understand what's meaning. thanks for your answer . 回答1: This means that the server you sent the request to responded with status code 14: Unavailable. This is supposed to be a temporary status, so you should be able to successfully make the request just by sending it again. 来源: https://stackoverflow.com/questions/38893402/nodejs-grpc-error-with-error-code-14

TLS ALPN in Python 2.7

烂漫一生 提交于 2019-12-12 00:21:43
问题 I'm working on some HTTP/2 client and I want to add SSL support. According to the RFC, the negotiation on the protocol is made using the ALPN protocol. Is there an implementation of ALPN in python 2.7? (I know there are HTTP/2 client implementations, but I want to write it myself) Thanks! 回答1: Please use the documentation and simply search for "alpn". It is well documented, like: SSLContext.set_alpn_protocols(protocols) Specify which protocols the socket should advertise during the SSL/TLS

File Upload support of Jmter HTTP2 sampler

北慕城南 提交于 2019-12-11 19:55:02
问题 I would like to use the "File Upload" option in the HTTP2 sampler to load test a server that supports HTTP2 with different message sizes. I have tried out the "File Upload" option in the HTTP2 sampler for this and observed that the path provided for the "file path" getting removed when we move across the other samplers, therefore it's not possible to use the file upload option in the HTTP2 sampler. After moving to another sampler, "file path" got removed. May I know how can send different

Sending Http2 Request to GRPC Server Node, Illegal Buffer

狂风中的少年 提交于 2019-12-11 16:17:09
问题 I am attempting to utilize protobuf.js and provide it a transport layer (rpcimpl) since it is transport agnostic. I can successfully convert all the proto files and to a direct grpc Client and Sever via protobuf (loadSync, lookup) to grpc's (loadObject). This allows me to get a concrete grpc implementation of server and client up with tests. The next step was to test a protobuf client (instable) to grpc server stable. This is more out of curiosity to see if we can be independent of grpc's

How do I do multiplexing on OkHttp?

可紊 提交于 2019-12-11 16:01:38
问题 I see some older questions about using SPDY (though the code has changed significantly since then), but no insights into how to properly leverage multiplexing and/or pipelining in OkHttp. I've gone through all the examples and have yet to see anything specifically referring to this. Is this something that is automatically done? 回答1: It’s automatic. If you have a server that supports HTTP/2, and a client that supports HTTP/2, it’ll do the right thing. 来源: https://stackoverflow.com/questions

How to enable http/2 in Weblogic server

独自空忆成欢 提交于 2019-12-11 14:58:51
问题 I want to enable http/2 for Weblogic 12c server . I could not find documentation for enabling http/2. 回答1: You can't, not yet. HTTP/2 is in the servlet 4.0 specification. The current release of WebLogic (12.2.1.3) implements servlet 3.1. The next major release which should support Java EE 8 (and thus servlet 4.0) should be out this year. 来源: https://stackoverflow.com/questions/49010845/how-to-enable-http-2-in-weblogic-server

Weird HTTP/2 HPACK encoding in Firefox

走远了吗. 提交于 2019-12-11 12:22:38
问题 I'm working on a server-side HTTP/2 implementation and using Firefox as a test client. Sometimes I get a request that looks wrongly encoded by FF. But before blaming FF I'd like to confirm with you if I'm decoding the HPACK data properly. Here is the original request (sorted by name as seen in the Firefox dev console): GET /images/rewards/icon-profile-on.png?81aa8356289ae0f1e4715f4f04f681cfe85147f0 Accept: */* Accept-Encoding: gzip, deflate, br Accept-Language: en-US,en;q=0.5 Connection: keep

Browser-side suggested HTTP/2 server push

夙愿已清 提交于 2019-12-11 12:15:47
问题 Are there any specific spec'd processes that a browser client can use to dynamically encourage a server to push additional requested items into the browser cache using HTTP/2 server push before the client needs to actually use them (not talking about server-side events or WebSockets, here, btw, but rather HTTP/2 server push)? 回答1: There is nothing (yet) specified formally for browsers to ask a server to push resources. A browser could figure out what secondary resources needs to render a
