LARTC - Jun 2005 - Flush route table on laod balancing between 3 connections

Hi,

I had made a script for make load balancing between 3 internet 
connections on the same gateway.

It work fine but I have juste one problem.

All my client (30 pc) use the SAME website (web.example.com), and load 
balancing is not effective because route to this site is in cache.

How I can flush route table without disconnecting connections in use 
with this site (web.example.com)

*ip route flush cache is a good solution?

Thanks,
Jeremy
