Or for a bigger offender, I noticed a couple of days ago that Rally (https://www.rallydev.com/ https://www.rallydev.com/) loaded over 5 MB of JavaScript from 3 scripts...being loaded 3+ times each (each one is over 600 KB)! Each script seemed to contain their own copy of ExtJS. Each script returns a 200, and doesn't use a 304 either on each load :( .
