Hi,
I noticed that HttpAttributes are not copied in ServerRequest.
In a Spring Boot application, I would like to pass a userId inside a WebFilter using HttpAttributes, and then later retrieve this value in LogbookWebFilter via an AttributeExtractor in order to include it in the logs. However, in my AttributeExtractor, I see that all HttpAttributes are empty.
This looks similar to what was fixed in PR #1805 for a different class (ClientRequest.java), but it seems that ServerRequest is missing the same behavior.
Is there a particular reason for not copying HttpAttributes in ServerRequest?
If not, I'd be happy to create a PR to address this.
Thanks!
