Re: [OT] Suggestion: http request bundle

David,

Since browsers are currently configured to load HTML pages in a rather
slow and piecemeal manner, one can obtain performance improvements by
reducing the number of JS and CSS files required on initial load.

So my comment was simply that Doug's suggestion about reducing the
number of individual files an HTML file is dependent, actually has
performance benefits.

These benefits to HTML page loading seem both on-topic, and don't
require reconfiguring every server, proxy and browser...which you seem
to be suggesting is "all you need to do"! :)

Regards,

Mark
