I am really looking for something that will change the ethernet card that my computer uses whenever a 404 error is recieved from a website. I have some type of simple command line script that will change the ethernet cards at a designated time interval, but I really need something that will try and access a website. If a 404 error is returned within a few seconds, the ethernet card my computer uses would be changed automatically. Please ask any questions as I am really looking for a solution!
