    16521494    The HTTP-version ABNF production has been clarified to be case-
    1653     sensitive.  Additionally, version numbers has been restricted to
     1495    sensitive.  Additionally, version numbers have been restricted to
    16541496    single digits, due to the fact that implementations are known to
    16551497    handle multi-digit version numbers incorrectly.  (Section 2.6)

    391 
    392     Each Hypertext Transfer Protocol (HTTP) message is either a request
    393     or a response.  A server listens on a connection for a request,
    394     parses each message received, interprets the message semantics in
    395     relation to the identified request target, and responds to that
    396     request with one or more response messages.  A client constructs
    397     request messages to communicate specific intentions, and examines
    398     received responses to see if the intentions were carried out, and
    399     determine how to interpret the results.  This document defines
    400     HTTP/1.1 request and response semantics in terms of the architecture
