Chrome has special internal "pages" that give you all sorts of awesome information about what is going on under the hood. I spent about 20 minutes compiling all the pages I could find before I found the grandaddy of them all:
chrome://chrome-urls will list all the internal Chrome pages.
One that you are going to want to keep in your back pocket for any kind of network debugging is
chrome://net-internals/, especially if you are doing cool stuff with SPDY
