Checking age of document without get()'ing it

I'd like to be able to find out if a page has changed since the last time I
retrieved it, without having to retrieve it all over again. Not all webmasters
use the meta date tag in their headers, so that is not a fool-proof method.
Because getting the web data is the most time consuming method of my entire
script, I'm looking to cut that down if the data is old. Is there such a way?
Thanks
Thomas
