IFWXGetXByY

This interface allows a filter to modify the result of remote gethostbyname or gethostbyaddr calls made by a Firewall client.

Methods in Vtable Order

IUnknown Methods	Description
QueryInterface	Returns pointers to supported interfaces.
AddRef	Increments the reference count.
Release	Decrements the reference count.

IFWXGetXByY Methods	Description
Deny	Denies the name-resolution request.
SetResult	Sets the hostent structure that will be returned.

Implementation

This interface is implemented by the Firewall service.

Remarks

The IFWXGetXByY interface essentially overrides the gethostbyname or gethostbyaddr functions, returning a hostent structure with different contents than would have been returned by the unfiltered calls. The filter has to call this interface from within IFWXSessionFilter::FirewallEventHandler.

A typical use of this interface would be to return an IP address other than that requested by the client; that is, to redirect the request.
