How to flush route table in windows

Question

I am trying to write a program that changes the default gateway of network time by time  But it seems that there are caches on the route table in every process so that I cannot control the network behavior accurately  Can I just flush route table to that process   For example if I executed an Iexplore exe first  then changed the default gateway to a Korean vpn  IE still went to amercia default gateway  But if I change the default gateway first and then execute Iexplore exe  it went to Korea   So how can I flush the route table cache  Thanks

You can open a command prompt and do a   route print   and see your current routing table     You can modify it by   route add    d d d d mask m m m m g g g g  route delete d d d d mask m m m m g g g g  route change d d d d mask m m m m g g g g   these seem to work   I run a ping d d d d -t change the route and it changes    my test involved routing to a dead route and the ping stopped

route -f causes damage  So we need to either disconnect the correct parts of the routing table or find out how to rebuild it

In Microsoft Windows  you can go through by route -f command to delete your current Gateway  check route     for more advance option  like add   delete etc and also can write a batch to add route on specific time as well but if you need to delete IP cache  then you have the option to use arp command
