RFC 6455 -- Implemented incorrectly -- Origin not required.

[schancel]

Line 84 of websocket.d should be changed:

    if( !(isUpgrade &&
          //pOrigin &&
          pUpgrade && *pUpgrade == "websocket" &&
          pKey &&
          pVersion && *pVersion == "13") )

The request MUST include a header field with the name |Origin|
[RFC6454] if the request is coming from a browser client. If
the connection is from a non-browser client, the request MAY
include this header field if the semantics of that client match
the use-case described here for browser clients. The value of
this header field is the ASCII serialization of origin of the
context in which the code establishing the connection is
running. See [RFC6454] for the details of how this header field
value is constructed.

Thanks. The code was written before the RFC was published, so there may actually be some more small differences left.
