Keep realserver IP as source in CSS

[shanilkumar2003]

Hi

Is there any way to keep real server IP address as source in the requests instead of VIP in CSS configuration.

Thanks

Hi Shanil,

I may be able to help if you explain a bit more in detail what you are trying to achieve.

If you try to establish a connection an IP address (in this case the VIP), but the reply comes from a different one (the rserver), the connection would fail, so what would be the point of getting the real server IP instead of the VIP?

Hi Shanil,

As I mentioned in my first email, if connections is sent towards the VIP address but the reply comes from the server, the client will reset the connection, so what you are trying to do doesn't make sense.

I don't see any reason why clients should be aware of the server that replied to the request (that's precisely one of the objectives of load-balancing, doing it transparently for the user, showing only the virtual server), but, if you really need to do it, I would suggest you to insert a cookie or header in the replies identifying the server.

This requirements is for our system admin team to know which real server serving the request, and i need this only for Exchange. Could you please advise the configuration for  insert a cookie or header in the replies identifying the real server in CSS?

Hi Shanil,

Adding headers or cookies to requests is something done by the servers themselves. I cannot help you with that.
