I tested this, and it works wonderfully. Thanks Christian! I'm still 
trying to figure out whether it makes sense for my setup -- the 
inevitable thing I left out is that we wanted people to be able to 
define their own CSS files to "skin" the site (sorry -- there are so 
many factors and details with this app). So if you really want to cache 
the HTML, you have to make the href to the CSS go to a universal 
redirect cgi, which sends the browser to the actual CSS. In other 
words, now each page view is invoking mod_perl twice, and possibly 
thttpd two times on top of that -- as opposed to one call to mod_perl.

So the question becomes: how much real advantage is there to using 
thttpd instead of Perl's open() and print()? I know the answer is 
"benchmarking," but as a final question on this topic, I wanted to see 
if people had a hypothesis/opinion. Two light hits to mod_perl 
resulting in one or two thttpd hits, or one heavier(?) hit to mod_perl?
