Virtually all Web servers require cookies. Cookies allow an application to store information on your customers computer so that their system can keep track of information more efficiently. From time to time, shoppers may voice concern about storing information on their computers because of the threat of viruses and other network paranoia. However, privacy concerns surrounding cookies are technically unfounded. Since most Web servers require cookies to operate, cookies are in fact a basic requirement on most Web Servers including Internet Information Servers (IIS) and Netscapes' web server. Since cookies are required by the actual Web servers, this issue is irrelevant since it has become a fundamental requirement to view most websites.
SalesCart does not specifically use cookies, but does rely on session information stored by the IIS Web server or by the PHP server. Thus, the Web server itself does require cookies and since SalesCart uses the web server it requires cookies indirectly.
