How to keep connection alive in Java 11 http client

阅读更多关于 How to keep connection alive in Java 11 http client

问题 I'm using the Java 11 HttpClient with HTTP/2 and need to keep connection alive for few minutes, but the builder does not have the option to set it. Is there a way to specify this and make client keep the connection alive for some time? 回答1: If you build a standard HttpClient e.g. using HttpClient.newHttpClient(); by default a connection pool is created. This pool keeps the connections alive by default for 1200 seconds (20 minutes). If you want to change the keep-alive timeout you can do so

问题 Here's my code: HttpClient client = HttpClient.newHttpClient(); HttpRequest request = HttpRequest.newBuilder() .uri(URI.create("http://127.0.0.1:8081/")) .header("Host", "test.example.com") .build(); client.send(request, HttpResponse.BodyHandlers.ofString()); As a result I see that the above code sends: GET / HTTP/1.1 Connection: Upgrade, HTTP2-Settings Content-Length: 0 Host: 127.0.0.1:8081 HTTP2-Settings: AAEAAEAAAAIAAAABAAMAAABkAAQBAAAAAAUAAEAA Upgrade: h2c User-Agent: Java-http-client/10

How do I send a HTTP/2 POST request in PHP

阅读更多关于 How do I send a HTTP/2 POST request in PHP

I found a similar question at Sending HTTP/2 POST request in Ruby But I want to update my server with PHP The new Apple push notification HTTP/2 based API described here: https://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/APNsProviderAPI.html Anyone with HTTP/2 experience help me with making a request as a client in PHP. 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

What is the difference between HTTP/1.1 pipelining and HTTP/2 multiplexing?

阅读更多关于 What is the difference between HTTP/1.1 pipelining and HTTP/2 multiplexing?

Is it because it requires the responses to be made to client in the order of request that causes the head of line blocking problem in HTTP 1.1? If each request takes exactly an equal amount of time, then there won't be head of line blocking and HTTP 1.1 pipelining and would perform same as that of HTTP/2 multiplexing? (let's say there is no request priority in HTTP/2 requests and disregard other changes of HTTP/2 such as header compression, binary, etc.) HTTP/1.1 pipelining still requires the requests to be returned in full, in the order requested. HTTP/2 allows the requests responses to be

Why bundle optimizations are no longer a concern in HTTP/2

阅读更多关于 Why bundle optimizations are no longer a concern in HTTP/2

I read in bundling parts of systemjs documentation that bundling optimizations no longer needed in HTTP/2 : Over HTTP/2 this approach may be preferable as it allows files to be individually cached in the browser meaning bundle optimizations are no longer a concern. My questions: It means we don't need to think of bundling scripts or other resources when using HTTP/2? What is in HTTP/2 which makes this feature enable? HTTP/2 supports "server push" which obsoletes bundling of resources. So, yes, if you are you using HTTP/2, bundling would actually be an anti-pattern. For more info check this:

Is HTTP/2 a stateless protocol?

阅读更多关于 Is HTTP/2 a stateless protocol?

问题 From my understanding, HTTP/2 comes with a stateful header compression called HPACK . Doesn't it change the stateless semantics of the HTTP protocol? Is it safe for web applications to consider HTTP/2 as a stateless protocol? Finally, will HTTP/2 be compatible with the existing load balancers? 回答1: HTTP/2 is stateless. Original HTTP is a stateless protocol, meaning that each request message can be understood in isolation. This means that every request needs to bring with it as much detail as

问题 Tomcat 8.5 , which will be the default in Spring Boot 1.4 , (to be released tomorrow) supports http2 . How can http2 be enabled in a Spring Boot application? 回答1: You need to add the HTTP 2 upgrade protocol to Tomcat's connector. You can do that by customizing the embedded Tomcat container: Java 8: @Bean public EmbeddedServletContainerCustomizer tomcatCustomizer() { return (container) -> { if (container instanceof TomcatEmbeddedServletContainerFactory) { (
