Dear Martin,

Thank you very much for your review.

Re 4.3.1.3: The reference is a mistake indeed.  Amazing that nobody 
spotted it before :-(  We will fix it to be RFC 7540.

Re 4.3.3.1: TCP persistence allows to send multiple HTTP requests using 
a single TCP connection.  We got used to this term during the drafting 
sessions; but I think a more precise and more frequently used term in 
the industry is "HTTP persistence".  Does it improve the text from your 
point of view if we rename "TCP persistence stack" to "HTTP persistent 
connections"? (https://en.wikipedia.org/wiki/HTTP_persistent_connection)

Re 4.3.1.1, 4.3.2.1: Your question regarding delayed ack requires more 
analysis with contributors.  Please bear with us.  I hope to have a 
coordinated response for you later today.

Best regards, Carsten
