in the normal way (no C<E<lt>PerlE<gt>> section required).
+There is an even simpler way to save that last C<stat()> call. Instead
+of using C<PerlTransHandler> combined with:
+ Alias /foo /
+
+we can use:
+
+ AliasMatch ^/foo /
+
+which in the current implementation (at least in apache-1.3.28)
+doesn't incur the C<stat()> call. Using the regex instead of prefix
+matching might slow things a bit, but is probably still faster than
+the C<stat()> call.
