opening multiple browser windows

Question

i need to find out how to open multiple browser windows. currently, i use: ProcessStartInfo sInfo = new ProcessStartInfo(url); Process.Start(sInfo); where "url" is a string which is the url i want to open up. the "url" passed varies however, and i don't want the program to open "url1" and "url2" in the same browser window (which is what is happening at the moment). what i want is for "url1" to be opened in one browser window, then "url2" to be opened up in a second, separate window. how do i do this? anyone have ideas?
