HTTP Ping Question

I have a few http servers in the network that I need to ping to find out which server is the closest route to send a service request.  I need to know what is the most efficient solution to this problem.  Please send suggestions.  This solution will be implemented in a COM component.


Thanks in advance

This is a difficult problem without access to a "map" of the available routes.  A series of ICMP ECHO (i.e. PING) packets can be used to trace a network route from end to end (i.e. the common traceroute program) but this is not only time-consuming to run, but can cause you to be labelled a poor "netizen" by those being pinged if you do it too often.

Now if this is a private network and its topology is relatively stable, you may be able to make some sort of database of optimal route that machines could use.  For example, anytime A wants to talk to B it would query the database for the best route from A -> B.  Similarly, if it wanted to talk to C, it would again ask.

Seems like a lot of trouble though.  Usually network administrators setup routers and servers in such a manner as to make things work pretty smoothly for most situations.  So is this really a programming problem or might it be better solved by some network evaluation and engineering?
