Hi @annah_brown
So not the easiest thing to accomplish. However saying that, you could do something like:
(function(sub_domain, cookie_name, a,b,c,d, e){
if (location.host === sub_domain) {
a = (new Date()).getTime();
b = utag.loader.RC(cookie_name);
c = a + parseInt(utag.cfg.session_timeout);
d = a;
if (!b) {
b = {};
} else if (b.ses_id && typeof b._st != "undefined" && parseInt(b._st) < a) {
delete b.utag_main.ses_id;
}
if (!b.ses_id) {
b.ses_id = d + '';
b._ss = b._pn = 1;
b._sn = 1 + parseInt(b._sn || 0);
} else {
d = b.ses_id;
b._ss = 0;
b._pn = 1 + parseInt(b._pn);
b._sn = parseInt(b._sn);
}
if (isNaN(b._sn) || b._sn < 1) {
b._sn = b._pn = 1;
}
b._st = c + '';
e = utag.cfg.domain;
utag.cfg.domain = location.host;
utag.loader.SC(cookie_name, {
"_sn": b._sn,
"_ss": b._ss,
"_pn": b._pn + ";exp-session",
"_st": c,
"ses_id": d + ";exp-session"
});
utag.cfg.domain = e;
}
}("sub.domain.com", "utag_sub_domain"));
This can be placed into a JS extension, scoped to DOM Ready. Or "All Tags" with "Before Load Rules" selected. If the later you will need to wrap the above code in a block like:
if (!utag.sub_domain_count) {
//Insert other block of code here
utag.sub_domain_count = true;
}
This will now give you an additional cookie on the sub domain, that contains counters just for that domain, as well as having the main cookie, with the overall counter.
Hopefully this helps.

Adrian
