What is the best library for HTTP/1.1 persistent(“Connection: Close”) connections in Java?

Question

I must choose a library for connecting to http endpoint. Http connection version is "1.1" . Server sends data to client continuously after opening the connection. So, connection is persistent; "Connection: Close" .

For this purpose, Which library is better? Is there any benchmark of these libraries such as performance, reliability etc.?

1. Apache Http Client?

2. HttpURLConnection(Standart Java Http Library)?

Answer 1

there is this legacy HttpUrlConnection class in JDK, and there's a new API in JDK 11, that supports both HTTP/1.1 and 2. It contains a new module called java.net.http which exports a package of the same name and is defined in JDK11

module java.net.http {

  exports java.net.http;
}

here is a very good article on the new JDK11 API
