   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.
