So to clarify, it sounds like you have a web application which tracks visitors via cookie.
Usually, server-side technologies (like ASP.NET. java servlets, and php) track unique visitors via cookie, but this is a dynamic value per visitor. Are you also tracking a campaign code in a specific cookie too?
When you record a clean (cache-cleared) scenario in LoadUIWeb, any cookies used during the recording are captured in the scenario requests and responses. If you need to data-drive your use of cookies in your recorded scenario(s), you can use the 'cookie replacers' functionality and select a variable you've already set up to get its values from a data source (like a spreadsheet).
