Why would there be a POST request with a referer of google.com?
===

I notice that my ASP.NET web app sometimes gets POST requests with the REFERER being a google.com URL.  How is that possible?  Is this some kind of hacking attempt?

Here are some of the more interesting HTTP values (I have replaced my real site with "mysite.com"):

    HTTP_REFERER = http://www.google.com/gwt/x/e?wsc=bf&wsi=d9f494c200f04c82&u=http%3A%2F%2Fwww.mysite.com&ei=65oLUNikApHoxAKykMHqBA&whp=1view_unadapted%3B2http%3A%2F%2Fwww.mysite.com     
    REQUEST_METHOD = POST     
    HTTP_COOKIE = ASP.NET_SessionId=eakdubyv3bfj33l0adtyhamc 
    HTTP_USER_AGENT = KWC-Buckle/ABO1107 UP.Browser/7.2.7.2.551 (GUI) MMP/2.0     
    CONTENT_LENGTH = 195 
    CONTENT_TYPE = application/x-www-form-urlencoded 
    SCRIPT_NAME = /cgi/webloginscript.aspx 
    SERVER_PORT = 443 
    SERVER_PORT_SECURE = 1 
    HTTP_X_WAP_PROFILE = "mms.mycricket.com" 
    HTTPS = on
