问题 I read about new feature in http2 RST_STREAM : HTTP/2 adds the RST_STREAM frame to allow a client to change its mind; if the browser navigates away from a page, or the user cancels a download, it can avoid having to open a new connection without wasting all of that bandwidth. How can do this?How Browser can do this?Is there any change in code? 回答1: The browser initiates a request and then changes its mind, either with the user navigating away or by cancelling. In HTTP/1.1, the only choice to

问题 The bundling of JS and CSS files won't be necessary in HTTP/2, but what about image sprites? Looking at the demo it seems that it already works way faster than HTTP/1.1, but won't bundling images into sprites make it even faster? I mean, won't the PNG's optimization algorithms work better when all the data is in a single file? 回答1: It depends of your image(s) sizes and format. If the images are big enough, you won't gain much by using sprites, but for small images there are significant gains,

问题 After some research, I was surprised that I did not not find any resource on HTTP/2 support in Tomcat. Changelogs of 8.0 indicate an experimental support of SPDY and wiki refers to HTTP/2 as a supported spec (http://wiki.apache.org/tomcat/Specifications) but I don't find any tutorial on it. Do you know if it is already possible to enable HTTP/2 on Tomcat? If the answer is yes how I can do that? 回答1: Tomcat does not yet support HTTP/2. HTTP/2 support is planned for Tomcat 9 onwards. It may get

问题 I'm looking for java client that can connect to a HTTP/2 based server.. The server is already supporting HTTP/2 API. I don't see the most popular Apache Http client https://hc.apache.org/ still supporting HTTP/2. Does Apache have some implementation for Java client already that supports Http/2? If not, Is there some java client that supports connecting to HTTP/2 preferably on Java 7? 回答1: Jetty's provides two HTTP/2 Java client APIs. Both require Java 8 and the mandatory use of the ALPN, as

问题 I am trying to use the new Apple Push Notification API, which is based on HTTP/2. I found the http-2 Ruby gem, but the documentation isn’t clear about how to make requests as a client. How to make a HTTP/2 request in Ruby/Rails? 回答1: There is an example of creating HTTP/2 client in this file. It could be adapted to APN requests like this: require 'socket' require 'http/2' payload = '{"foo":"bar"}' device_token = '00fc13adff785122b4ad28809a3420982341241421348097878e577c991de8f0' # example sock
