HTTP cookies are small files of alphanumeric text that web servers put on web clients. Cookies monitor the page a web client is on, to enable the web server to send more pages in the correct sequence. Web servers also use cookies to collect information about an end user. Many websites use cookies for authentication and other legitimate functions, and cannot operate correctly without cookies.
The HTTP proxy gives you control of the cookies in HTTP responses. You can configure rules to strip cookies, based on your network requirements. The default rule for the HTTP-Server and HTTP-Client proxy action allows all cookies. You can add, delete, or modify rules.
The proxy looks for packets based on the domain associated with the cookie. The domain can be specified in the cookie. If the cookie does not contain a domain, the proxy uses the host name in the first request. For example, to block all cookies for nosy-adware-site.com, use the pattern: *.nosy-adware-site.com. If you want to deny cookies from all subdomains on a website, use the wildcard symbol (*) before and after the domain. For example, *example.com* blocks all subdomains of example.com, such as images.example.com and mail.example.com.
