by-pass proxy authentication

[kboy168]

Hi all,

I know that it's possible to by-pass the proxy authentication of certain URL. However, is it possible to limit that to the requests coming from particular servers? ie. URL_A from Server_S will not require proxy authentication, but URL_A from Server_Y will require proxy authentication.

If this can be done, can someone tell me what's the step to do that?

Thanks,

k
