I have a fresh 3.5.1 installation - default theme, no plugins.
Running HTTPFox on Firefox shows that after a GET-request of any given page in Wordpress has finished loading, a GET-request is sent for the
<link rel='next' title='Next Page Title' href='http://www.domain.com/next-page/' />
00:10:04.992 0.556 698 245 GET (Aborted) text/html (NS_BINDING_ABORTED) http://www.domain.com/next-page/
My question - is this on purpose? Is wordpress doing some kind of preloading? I'd like to understand why it is doing this.
