No, that's not how they do it. I just turned off JavaScript and 
cookies, went to amazon, and successfully added an item to my cart. I 
think they do it through extensive URL rewriting. Remember a GET 
request can run a program on a server just as easily as a POST 
request. A POST cannot do anything a GET can't do. The difference is 
that a POST operation should not be cached or repeated because it may 
obligate the client, while a GET is supposed to be SAFE.
