Description
Cookies are used to exchange data between the web server and the client. Cookies, such as a session cookie, may contain session information and user credentials used to maintain a persistent connection between the user and the hosted application since HTTP/HTTPS is a stateless protocol. vSphere UI is bound to the "/ui" virtual path behind the reverse proxy, and its cookies are configured as such. This configuration must be confirmed and maintained.
