bug: with apache 2, apache_lookup_uri("/directory") spits out a warning and fails to return anything. apache_lookup_uri("/directory/") works.
another bug: virtual("something") forces a header flush. I know it's documented, but it would be rather wonderful if it didn't do this. You never ever want to flush headers when you're using virtual() to include a dynamic file such as a PHP or Perl file, which excludes virtual() from being used on most of any website's contents :-(.

It's a very usefull function but it doesn't show all outputs. For example I only see:
[status]
[the_request]
[method]
[mtime]
[clength]
[chunked]
[content_type]
[no_cache]
[no_local_copy]
[unparsed_uri]
[uri]
[filename]
[path_info]
[allowed]
[sent_bodyct]
[bytes_sent]
[request_time]

A useful feature is that if you have content negotiation on (Options MultiViews) Apache will resolve the negotiation for you if possible. Thus www.example.com/blah will resolve to /base/blah.php or /base/blah.html or even /base/blah.en.html as appropriate.
