Suppose i have Cookie is a cookie for cookies, and my subdomain is sub.domain.com. Can I delete the cookie set for the main domain? I know that it is possible to read them, but is it possible to delete these cookies, or overwrite their values? "post-text" itemprop = "text">

Yes, a subdomain can set / eliminate a cookie for the main domain, but the main domain is set / end cookie for any subdomain Can not see the RFC 6265 section, (see point # 6), and Section 8.6 specifically tells how a subdomain can set a cookie for the main domain and it affects one of its subdomains.
