本網頁說明以下題目的概念：
Web application developers sometimes use hidden fields on web pages to save information about a client session. This technique is used, in some cases, to store session variables that enable persistence across web pages, such as maintaining the contents of a shopping cart on a retail web site application. The MOST likely web-based attack due to this practice is:
A.parameter tampering. 
B.cross-site scripting. 
C.cookie poisoning. 
D.stealth commanding.
