Re: Minutes of the Web Services Addressing / TAG joint meeting

RFC2617 allows a limited form of integrity protection on both requests 
and responses; see sections 3.2.2 and 3.2.3, especially with regard to 
the calculation of A2. While it's true that HTTP Digest authentication 
doesn't provide for integrity protection on HTTP headers (it's very 
messy), the Request-URI isn't a header, it's in the Request-Line.

That said, I'm not aware of any implementations that support this. 
Anybody else?

Also, SSL and TLS provide security for both HTTP headers and all of the 
request line EXCEPT for the hostname and port.

Cheers,
