Bandwith Tool

I am not sure if you have seen this tool before, but this allows you to see how much bandwidth any of your applications takes up. It is called Fiddler. The best thing is that it can give you a running tab on how heavy your web-page is, but if you are good at partitioning your code and style, the scripts and stylesheets will cache allowing the weight of you page to be noticeably smaller the second time around and so on. I will say that the capabilities of this tool cause it to be overwhelming at a glance, but once you use it for a while, you get used to it. Here is a link to it: http://www.fiddler2.com/fiddler2/version.asp
