Class ConnectionSpec

java.lang.Object

org.aoju.bus.http.ConnectionSpec

public final class ConnectionSpec
extends Object

Specifies configuration for the socket connection that HTTP traffic travels through. For https: URLs, this includes the TLS version and cipher suites to use when negotiating a secure connection.

The TLS versions configured in a connection spec are only be used if they are also enabled in the SSL socket. For example, if an SSL socket does not have TLS 1.3 enabled, it will not be used even if it is present on the connection spec. The same policy also applies to cipher suites.

Use ConnectionSpec.Builder.allEnabledTlsVersions() and ConnectionSpec.Builder.allEnabledCipherSuites() to defer all feature selection to the underlying SSL socket.
