Disabling back button (was: [thelist] Industry Associations)

[aardvark]

i could give you a JS solution, but i'm not going to... it's too easy to 
bypass, have it not work, or have other bizarreness cause it to fail...

instead, have your application handle this... perhaps you can set a 
cookie (which can be bypassed as well, even session-only 
cookies), or have a form variable that gets incremented by the 
server, or something... depending on how you are capturing data 
and processing it, there are a number of options...

by default, i set a session cookie that gets deleted when the 
browser is closed or when the customer goes to the beginning of 
the order process again (with a new cart)... i also do some script 
trickery on the final page to help account for the rest of the users...
