Yo!
This was a lot of work and it still isnt finished.
http://www.senior-aktuell.at/
The site is about a fair for older people in Vienna.
The visits will increase in the next month, up to 20000 daily, so I made a caching solution for the main pages(simply copy and save as static pages).
The biggest part is the exibitors directory, 240 pages at the moment. Of course: virtual pages, redirected with mod_rewrite like: /aussteller/link.html -> index.php?a_link=link
Those pages are dynamic (they may change hourly), but with cached query-results.
Design: elastic, with relative fontsizes (em,%), working stable on (I hope) also older browsers.
Some more in german:
