how to use Multiplexing http2 feature when uploading

由 瘦欲@ 提交于 2020-04-17 21:36:07
问题 There should be a significant improvement of performance using multiplexing http2 feature when uploading multiple files. And Java has an httpclient which supports natively the HTTP/2 protocol, so given that I tried to wrote the code for my own understanding. This task seems to be not easy as I thought initially, or on the other side it seems that I wasn't able to find a server able to use Multiplexing in upload (if exists). This is the code I wrote, anyone has thoughts about? HttpClient

Why does Xamarin Android fails to send GRPC/Http2 requests?

由 ぐ巨炮叔叔 提交于 2020-04-06 23:22:18
问题 I'm trying to run the xamarin forms sample from the Dot net conf 2019 keynote. I've hosted the grpc service and a .net core console application can get data from it without any issues. But when running the xamarin app, the ALPN negotiation(Client hello) happens with http 1.1 and therefore the grpc call fails. Source code available here Error message: Grpc.Core.RpcException: Status(StatusCode=Internal, Detail="Bad gRPC response. Response protocol downgraded to HTTP/1.1." Debugger reveals that

或许是 Nginx 上配置 HTTP2 最实在的教程了

某厂面试归来，发现自己落伍了！>>> 导读 从 2015 年 5 月 14 日 HTTP/2 协议正式版的发布到现在已经快有一年了，越来越多的网站部署了 HTTP2，HTTP2 的广泛应用带来了更好的浏览体验，只要是 Modern 浏览器都支持，所以部署 HTTP2 并不会带来太多困扰。 虽然 h2 有 h2c （HTTP/2 Cleartext） 可以通过非加密通道传输，但是支持的浏览器初期还是比较少的，所以目前部署 h2 还是需要走加密的，不过由于 Let’s Encrypt 大力推行免费证书和证书的廉价化，部署 h2 的成本并不高。 介绍 HTTP 2.0即超文本传输协议 2.0，是下一代HTTP协议。是由互联网工程任务组（IETF）的Hypertext Transfer Protocol Bis (httpbis)工作小组进行开发。是自1999年http1.1发布后的首个更新，HTTP/2 协议是从 SPDY 演变而来，SPDY 已经完成了使命并很快就会退出历史舞台（例如 Chrome 将在「2016 年初结束对 SPDY 的支持」；Nginx、Apache 也已经全面支持 HTTP/2 ，并也不再支持 SPDY），一般的大家把 HTTP2 简称为 h2，尽管有些朋友可能不怎么愿意，但是这个简称已经默认化了，特别是体现在浏览器对 HTTP2 都是这个简写的。 配置 普通的

Use HTTP 2 with HttpClient in .Net

由 半城伤御伤魂 提交于 2020-03-13 06:24:31
问题 I'm trying to request data over HTTP 2.0. I'm using the HttpClient from .Net Core 2.2. I'm on Windows 10 but will run on Linux in production. The problem is that the version on the response seems to always be "1.1". What I am doing wrong? using (var client = new HttpClient()) { using (var request = new HttpRequestMessage(new HttpMethod("GET"), "https://duckduckgo.com/" )) { request.Version = new Version(2, 0); var response = await client.SendAsync(request); Console.WriteLine(response.Version)

Using HTTP/2 with angularJS

问题 I am trying to find out ways to increase the performance of my web application when I stumbled upon HTTP/2. On reading about it, I got to know that it has very many features to increase website performance. Coming to the implementation part of it, I see that you only have to upgrade your browser to the latest version for it to come to use. Since my browser is already at the latest version, I see that all of my resources - CSS, JS and HTML files are served with HTTP/2. However, the data

Single bundle with minification vs multiple files over http/2

问题 What is the general recommendation when it comes to CSS and JS bundling: Is it better to bundle everything into one file or is it better to serve multiple files? I personally say that multiple files are better, especially with http/2, but there're good reasons for bundles: Minification and gzip have better results when everything is in one file, because of all the recurrences you typically have when writing lots of code. Serving multiple files on the other side improves caching and allows
