how to execute a test talking to two browsers opened using webdriver?

[sdudi]

i need to talk to two browsers , two different urls.
switch between them during run time.
can any one help?

I assume that two browsers are not affected with each other, hence you could create two instances of webdriver objects for the browser you want to perform test with.
