My browser can't distinguish my requests and when a server is off then it must forwarded to other servers automatically. I know in a real scenario, it solved by domain name. > If my configuration is OK, then Apache accepts a request from port 80, one of my servers is turned off and Apache must forward it to another server. I used " <VirtualHost *:80>" and not any IP. The configuration doesn't express this at all. Your configuration expresses one domain forwarded to one backend and a second domain forwarded to a second backend. I don't think what you describe is possible (there may be some obscure config to resemble it) or useful. No user has this expectation for a URL they're accessing. A service is either clustered behind a reverse proxy or it isn't. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
