haitao：
rfc2660里有这样的例子，而我截取得的SSL数据包没看到这样的明文格式的。。。

There is a link on the HTML page that was just returned, which Alice
dereferences, creating the HTTP message:
============================================================
GET /prize.html HTTP/1.0
Security-Scheme: S-HTTP/1.4
User-Agent: Web-O-Vision 1.1beta
Accept: *.*
============================================================
Which, when encapsulated as an S-HTTP message, becomes:
============================================================
Secure * Secure-HTTP/1.4
Content-Type: message/http
MAC-Info:31ff8122,rsa-md5,b3ca4575b841b5fc7553e69b0896c416,inband:alice1

============================================================
是不是rfc2660（s-http/1.4？）和SSL还是不一样的？
