I've been having some issue attempting to request a cookie through the use of JavaScript. Basically I'm taking a cookie value that I'm setting through the use of VBScript...then reading the value in a client side JS fuction to keep a DHTML effect I'm using the same from page to page. The issue that I'm having is not being able to read a cookie that has mulitple values.....
example)
<%
'Server side code in VBScript setting the cookie
Response.Cookies("userInfo")("menu1") = "closed"
Response.Cookies("userInfo")("menu2") = "open"
%>

The next bit of code is the JS code for reading the cookie, but I can't seem to get it to work for a cookie that has multiple data values...
<script LANGUAGE="JavaScript">

</script>

If anyone could lend a little insight on this one I'd be very grateful.......

alert(document.cookie);

execute that line, and you can see where the information is. Then you have to get it out of the string using regular expressions or substring functions.
