1. With 127.0.0.1 localhost domain name and IP cross domain? I tried, the local results do not cross domain, because hosts file on yao, or domain name and IP does not cross domain
2. qq.com and www.qq.com top-level domain and subdomain cross domain, in the picture can take to www.qq.com qq.com localstorage, does that mean the secondary domain name does not cross domain
