Example 1 with HTTP2_CONNECTION

use of software.amazon.awssdk.http.nio.netty.internal.ChannelAttributeKey.HTTP2_CONNECTION in project aws-sdk-java-v2 by aws.

    // close any connections when a GOAWAY is received, but we'd like to send a "GOAWAY happened" exception instead of just
    // closing the connection. Because of this, we use a go-away listener instead of a handler, so that we can send the
    // exception before the Http2FrameCodec closes the connection itself.
