First, do not use the proxy server situation:
REMOTE_ADDR = Your IP
Http_via = no value or no display
Http_x_forwarded_for = no value or no display
Second, the use of transparent proxy server situation: transparent proxies
REMOTE_ADDR = Proxy Server IP
Http_via = Proxy Server IP
Http_x_forwarded_for = Your real IP

Virtual Agent Mode-virtual ProxyVirtual proxy mode defers the actual time required for object instantiation. If a proxy object can handle a real object before it needs to work, the real object is not needed for the moment.Pros: The advantage of this approach is that when the application starts, it accelerates application startup because it does not require all objects to be created and loaded.disadvantage:
