Modified Domain Cookie blocking

It would be most helpful to see the response(s) where these cookies are being set. They may not be from your application, but could be from other applications on the britannia.co.uk domain. The __utma cookie is a Google Analytics cookie. The _mkto_trk cookie looks to be from a marketing company, Marketo. I couldn't find any info on the L6289 cookie. I'd guess it's something custom.

 

 

If you're not worried about the client modifying these cookies, you could either configure them individually as allowed modified domain cookies, or you could disable checking of domain cookies altogether. Unless we know of a specific issue in the application we're configuring a policy for with badly encrypted cookies we normally disable this check anyhow.
