Error description

While testing dynamic routing, SVT found an issue where a hang/timeout occurred waiting for a response. On investigation, it seems like the error comes from sending a request with Expect: 100-continue and waiting for the 100 response while using Netty. It appears that Netty does not send the 100 continue response at all.

Expected behavior

When receiving an expect 100 response the server should respond with a 100 continue response before sending the actual response of the request as seen in the packet trace below.

Current behavior

In Netty, we are seeing that the current implementation does not send a 100 continue response but jumps straight to the actual response of the request as seen in the packet trace below.
