Hi guys,<BR>The Cookies are being overwritten in case of multiple browser instances. I am thinking of writing a cookie and incrementing it by 1 whenever the browser is opened, and pass this as a querystring to the site and do something like this.<BR> <BR>Existing Cookie : Response.write("Ref")("RefID") = strRefID<BR>Proposed Cookie : Response.write("Ref" & qrystr)("RefID") = strRefID.<BR><BR>The only problem I see using this technique is, I need to pass the querystring to nearly 200 pages and update all the cookies.<BR><BR>Am I doing right ?? Or is there any other way of dealing with this.<BR><BR>Thanks a lot for looking into this.<BR>Any help is appreciated.<BR>
