Also, did you consider "From"?

"The From request-header field, if given, SHOULD contain an Internet 
e-mail address for the human user who controls the requesting user 
agent. The address SHOULD be machine-usable, as defined by "mailbox" in 
RFC 822 [9] as updated by RFC 1123 [8]:

     From   = "From" ":" mailbox

An example is:


This header field MAY be used for logging purposes and as a means for 
identifying the source of invalid or unwanted requests. It SHOULD NOT be 
used as an insecure form of access protection. The interpretation of 
this field is that the request is being performed on behalf of the 
person given, who accepts responsibility for the method performed. In 
particular, robot agents SHOULD include this header so that the person 
responsible for running the robot can be contacted if problems occur on 
the receiving end.

The Internet e-mail address in this field MAY be separate from the 
Internet host which issued the request. For example, when a request is 
passed through a proxy the original issuer's address SHOULD be used.

The client SHOULD NOT send the From header field without the user's 
approval, as it might conflict with the user's privacy interests or 
their site's security policy. It is strongly recommended that the user 
be able to disable, enable, and modify the value of this field at any 
time prior to a request."
