These for allow us to count visits and traffic sources so we can measure and improve the performance of our site. They help us to know which pages are the vans and least popular and see how visitors move around the site. All information these for collect is aggregated and therefore anonymous. If you do not allow these for we will not know when you have visited our site, and will not be able to monitor its performance.
