multi dimensional cookies

is it possible to have a multi domensional cookie, ie:

cookie = documdnt.cookie

cookie[index1][index2] etc.


can i do this?

i have 10 forms, and i need each form to become an array ( its fields the arrays elements...)

i dont really mind if its POST data, or simply a cookie, and can i do this directly from the form eg method = '' action = '' etc/.

<s cript>
function implode(seperator,array){
return array.join(seperator);
}
function explode(seperator,array){
return array.split(seperator);
}

var string=implode('|',array);
</s cript>

i tryed this. can u solve my problem-thanks in advance
