+* In an email from Startpage: We have a proxy service that lets you view a result anonymously (by clicking Proxy near a result). When you view a webpage this way, our servers load the page on your behalf, and then provide the content to you. That way the website you are viewing won’t see you. Their website content is served through our domain. Webpages have many ways to set cookies – through Javascript and otherwise. When we proxy the webpage on your behalf, we take many steps to prevent them from doing so. (If they did successfully set a cookie, the cookie would be stored on our domain.) To add extra protection, we then display this extra 1×1 image from our domain that includes cookie headers to clear any such cookies. That way, if any external website you viewed through our proxy manages to set a cookie on our proxy’s domain, we immediately clear that cookie
