It takes more than just that:

* if the partial URL starts with a /, it uses procotol and hostname as
André suggests

* otherwise, it takes the URL of the current page, trims the right-hand
side of the URL until it hits a /, then appends whatever you have as
your partial URL

+1

Lots of requests = site feels slow. We intentionally limit the amount of
junk we have in our UI so that everything feels snappy. Use CSS
liberally and avoid lots of images. Also, avoid tables that require a
large amount of data to load before the page can be laid-out correctly.

Also remember that many web browsers will not cache anything retrieved
via HTTPS, so you might want to play with some of your headers so things
like CSS files, images, etc. are in fact being cached by your clients.
