Question

Why aren't my cookies being set?

Answer

By default, utag.js will set cookies in the domain it is being loaded on. However, for security reasons, browsers do not allow cookies to be set on top-level domains (TLD), such as ".com", ".org" or ".co.uk". What you may not realize is that there are hundreds of actual domains that are also considered to be TLD, on which cookies are also restricted. 

Some common domains affected include:

In these cases where cookies cannot be set, you can override the cookie domain in the Publish Configuration settings. Please note that this is a global setting and applies to all environments you publish to.
