Coldfusion Cookie Issues

Hi Guys! I am trying to create a cookie and if the cookie exosts, expand that cookie with other values.

Well here is the code what i am trying todo:

<cfscript>
function listRemoveDuplicates(lst) {
var i = 0;
var delim = ",";
var asArray = "";
var set = StructNew();

if (ArrayLen(arguments) gt 1) delim = arguments[2];

asArray = ListToArray(lst, delim);
for (i = 1; i LTE ArrayLen(asArray); i = i + 1) set[asArray[i]] = "";

return structKeyList(set, delim);
}
</cfscript>
<cfset favlist = #ID# & "&" & #catname#>
<cfif NOT isDefined('cookie.favorites')>
	<cfcookie name="favorites" value="#favlist#">
<cfelse>
	<cfcookie name="favorites" value="#listRemoveDuplicates(ListAppend(favorites,'#favlist#',','))#">    
</cfif>

Code (markup):

The above code is just adding the ID and catname in cookie variable

favorites as ID & catname and when i check the values in the cookie, it shows me something like this:

favorite = 160&94, 123&66, 122&88

Okay Now in next page i just try to simply the Cookie by splitting.

I am trying to make that for every cookie. i should set up a value when one should contain like:

ID = 160

catName = 94

so that i can use them in my link to make a favorite link.

i am trying something like below:

first i am converting the list to array and then running a loop over array to see its results:

results appear like:

160&94
123&69

how do i furthur Split it to two variables and furthur use it:

Here is my little try:

<cfscript>
function split(str) {
    var results = arrayNew(1);
    var splitstr = ",";
    var treatsplitstrasstr = true;
    var special_char_list = "\,+,*,?,.,[,],^,$,(,),{,},|,-,&";
    var esc_special_char_list = "\\,\+,\*,\?,\.,\[,\],\^,\$,\(,\),\{,\},\|,\-";    
    var regex = ",";
    var test = "";
    var pos = 0;
    var oldpos = 1;

    if(ArrayLen(arguments) GTE 2){
        splitstr = arguments[2]; //If a split string was passed, then use it.
    }
    
    regex = ReplaceList(splitstr, special_char_list, esc_special_char_list);
    
    if(ArrayLen(arguments) GTE 3 and isboolean(arguments[3])){
        treatsplitstrasstr = arguments[3]; //If a split string method was passed, then use it.
        if(not treatsplitstrasstr){
            pos = len(splitstr) - 1;
            while(pos GTE 1){
                splitstr = mid(splitstr,1,pos) & "_Separator_" & mid(splitstr,pos+1,len(splitstr) - (pos));
                pos = pos - 1;
            }
            splitstr = ReplaceList(splitstr, special_char_list, esc_special_char_list);
            splitstr = Replace(splitstr, "_Separator_", "|", "ALL");
            regex = splitstr;
        }
    }
    test = REFind(regex,str,1,1);
    pos = test.pos[1];

    if(not pos){
        arrayAppend(results,str);
        return results;
    }

    while(pos gt 0) {
        arrayAppend(results,mid(str,oldpos,pos-oldpos));
        oldpos = pos+test.len[1];
        test = REFind(regex,str,oldpos,1);
        pos = test.pos[1];
    }
    //Thanks to Thomas Muck
    if(len(str) gte oldpos) arrayappend(results,right(str,len(str)-oldpos + 1));

    if(len(str) lt oldpos) arrayappend(results,"");

    return results;
}
</cfscript>
<cfdump var="#cookie#">
<cfset x = ListToArray(favorites)>
<cfdump var="#x#">
<cfloop index="n" from="1" to="#arrayLen(x)#">
<cfoutput>#x[n]#<br /></cfoutput>
</cfloop>

Please Show me a way how do i implement it
