How does IDzap solve my problem?
What happens in the background is that the request is first sent to www.idzap.com. The IDzap server makes a request using the identity of IDzap to obtain the page from companyA. When IDzap receives the page, the IDzap server adjusts the hyperlinks to make sure that subsequent requests through clicking the hyperlinks will also be made anonymously. The page content is then sent to the browser of the web user. In this way, companyA will never obtain any user specific information from the web visitor.
