New users would request the file, returning users would not. On average only about 30%-40% of users are return users. Caching also depends on the browser settings of each user. Take a look at my YSlow review for more tips on performance optimization. http://seifi.org/server/yslow-review-the-firebug-addon.html You are right to some respect mangofever.

So I don't know if you're 44 GB is realistic. Regarding the compression, I would have thought that Javascript files were mostly cached by the browser. So I don’t know if you’re 44 GB is realistic.

Bandwidth usage is becoming less/more of a consideration depending on the popularity of the website/app which you have developed. With this in mind sticking to the mainstay of keeping image sizes to a minimum and good clean markup should be first and foremost practice for the majority of developers/designers. However, if your site is attracting countless visitors then the above suggestions are priceless. Also, I think its worth pointing out once more that going down the compression route for files such as css/js etc really should be considered towards the end of the development life cycle. (tip! keep uncompressed backups) Nothing worse than trying to work backwards in order to take a step forward on a project you may not have worked on for several weeks. Even worse than that is some one else trying to work out what you did several weeks ago from a compressed file. Geoff Great article and lots of good points raised.
