Operation of Cookies

For example, if there are two domain names on a website, we need to consider the cookie under two domain names.

What we call cross-domain is lesport.com and le.com.

JS Cookie is not cross-domain, in order to prevent too large.

JS Add Delete and find a whole bunch of online. Recommended below.

We need to understand when the increase, such as the server has a return of the cookie, we need to temporarily add a front-end, must be added under the first domain name (level two domain name can also be added)
