Doing it on demand might be a mistake here, but we can also 
pre-compress the files since it is a static site.

You just run gzip on the files then serve them up with the proper 
headers.

here's a thing about doing it in apache

I don't know about vibe, but it is trivially simple in HTTP, so 
if it isn't supported there, it is probably a three (ish) line 
change.

Caching is the same deal btw, just set the right header and 
you'll get a huge improvement. "Cache-control: max-age=36000" 
will cache it for ten hours, without even needing to change the 
urls. (Changing urls is nice because you can set it to cache 
forever and still get instantly visible updates to the user by 
changing the url, but we'd probably be fine with a cache update 
lag and it is simpler that way.)

ETags are set right now and that does some caching, it could be 
improved further by adding the max-age bit tho.

This is an apache config of some sort too.

though I don't agree it should be one year unless we're using 
different urls, we should do hours or days, but that's how it is 
done.
