           Summary: In reply to: <p class="warning">Following HTTP
                    procedures here could introduce     serious security
                    problems in a Web browser context. For example,
                    consider a host with a WebSocket server at one path

In reply to:
<p class="warning">Following HTTP procedures here could introduce
    serious security problems in a Web browser context. For example,
    consider a host with a WebSocket server at one path and an open
    HTTP redirector at another. Suddenly, any script that can be given
    a particular WebSocket URL can be tricked into communicating to
    (and potentially sharing secrets with) any host on the Internet,
    even if the script checks that the URL has the right hostname.</p>

It SHOULD be possible to get the information from HTTP Status Codes 4xx and
5xx, to provide the ability to return useful information to the client, for
example, a "400 Bad Request" response with the following message "WebSocket
Version 8 or greater is required".
