HTTP filter for specific port

[Raziel]

Hi,
I need to know whether there is any option when adding a new HTTP
filter (using the provided SDK) to specify a specific port or listener
for the filter, meaning that this filter will be activated just if a
HTTP request is coming from this particular port and not for any HTTP
request which can cause a performance problems.
Please advise me.

Thanks.

You can implement this functionality.
A new server variable called LISTENER_GUID will give you the GUID (as a
string) of the network listener or web listener you connected through. You
can use IS_REVERSE_PROXY (or REVERSE_PROXY) to know the type of listener to
get.

You can also use the SERVER_PORT variable to know which port the request
came through.

Use these values to decide if your filter should act or not. You can extend
the ISA UI by means of a snap-in to provide a user-friendly interface for
the filter - see the SDK.
