A read-only enumerated value reporting whether the controller's Web Proxy service is running, stopped, or disabled. If the controller uses this proxy to intercept or redirect user HTTP traffic, for example toward the captive portal or content filtering, a stopped proxy changes how, or whether, user web traffic gets handled. If unauthenticated users start reaching the open internet without being redirected to the portal, the admin would check whether webProxyService has stopped unexpectedly.
