Technically There are several technical reasons why HTTP/2 is much better and easier to handle over HTTPS: Doing HTTP/2 negotiation in TLS with ALPN is much easier and doesn’t lose round-trips like Upgrade: in plain HTTP does. And it doesn’t suffer from the upgrade problem on POST that you get with plain-text HTTP/2. N% of … Read more
With the standardization of the HTTP Client API, the incubated APIs are now removed. The module name and the package name of the standard API will be java.net.http which can now be used as – module <yourModuleName> { requires java.net.http; } Also, adding to the tally, the applications, frameworks(like Maven, Gradle etc) or IDEs relying … Read more
The CURL extension for PHP >= 5.5.24 has support for HTTP/2. (since this commit) You also need a libcurl installed — the underlying library that the curl functions use — with HTTP/2 support enabled. That means a libcurl newer than 7.38.0 but really, the newer the better. Libcurl has to have been built with HTTP/2 support … Read more
You can just check it in: Chrome Dev Tool (F12) → Network → Protocol. It will tell you the protocol used and the domain of each transfer. Legend http/1.1 = HTTP/1.1 h2 = HTTP/2 Note: If you cannot see the Protocol column, just right-click on any header and check the “Protocol” label.
The bundling optimization was introduced as a “best practice” when using HTTP/1.1 because browsers could only open a limited number of connections to a particular domain. A typical web page has 30+ resources to download in order to be rendered. With HTTP/1.1, a browser opens 6 connections to the server, request 6 resources in parallel, … Read more
Will likely be one of two reasons: You are using anti-virus software and it is MITM your traffic and so downgrading you to HTTP/1.1. Turn off https traffic monitoring on your AV to connect directly to the server. You can check if this is the case by using an online tool to test your site … Read more
Let’s clarify a few things: My understanding is that http2 renders optimization techniques like file concatenation obsolete, since a server using http2 just sends one request. HTTP/2 renders optimisation techniques like file concatenation somewhat obsolete since HTTP/2 allows many files to download in parallel across the same connection. Previously, in HTTP/1.1, the browser could request … Read more
It is partly about making more things use HTTPS and encourage users and servers to go HTTPS. Both Firefox and Chrome developers have stated this to be generally good. For the sake of users and users’ security and privacy. It is also about broken “middle boxes” deployed on the Internet that assume TCP traffic over … Read more
Browsers impose a per-domain limit of 6-8 connections when using HTTP/1.1, depending on the browser implementation. This allows at most 6-8 concurrent requests per domain. With HTTP/2, browsers open only 1 connection per domain. However, thanks to the multiplexing feature of the HTTP/2 protocol, the number of concurrent requests per domain is not limited to … Read more
1.Make sure you are on the latest version of Windows 10. 2.Install WinHttpHandler: Install-Package System.Net.Http.WinHttpHandler 3.Extend WinHttpHandler to add http2.0 support: public class Http2CustomHandler : WinHttpHandler { protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, System.Threading.CancellationToken cancellationToken) { request.Version = new Version(“2.0”); return base.SendAsync(request, cancellationToken); } } 4.Pass above handler to the HttpClient constructor using (var httpClient = … Read more
