Do you mean re-load as in re-transferring data over the network? If so, that
can be avoided simply by caching. If you mean going through the resource
selection algorithm again, I'm not sure I see why that would be a problem.

At large, I have yet to see (or understand) a case where it's not sufficient to
just go through the resource selection algorithm again and treat it as a
quality-of-implementation issue how well a browser is able to reuse the data
and decoding pipelines it already has.
