Load balance related quistion

Is it possible to identify which client has accessing the server after passing through f5 load balance? or in other words can the application servers know from which client does the request come?

Hi,

 

If you don't use any type of SNAT towards your pool members, they will see the Client IP address connecting to them.

 

If you want to use SNAT and still have the back-end recognize the client address, you can use the X-Forwarded-For header with an HTTP profile. http://en.wikipedia.org/wiki/X-Forwarded-For

 

Hope this helps.
