IFWXGetXByY

IFWXGetXByY allows you to override the gethostbyname or gethostbyaddr function. A typical use of IFWXGetXByY is to return an IP address other than that requested by the client, thus redirecting the request. IFWXGetXByY can also cause the gethostbyname and gethostbyaddr functions to fail, so that the Firewall service will return a "Host Not Found" message.

Notes to Implementers

The filter must call this interface from within the IFWXSessionFilter::FirewallEventHandler function.

Typical Implementations
