http status code for directories without trailing '/'

[Simon Spero <se...@tipper.oit.unc.edu>]

I was just explaining to about how urls that refer to directories should 
always end in a trailing slash, and how the server issues a redirect to 
make sure things work. I was using apache 0.6 to demonstrate, and I 
spotted a slight problem in the returned status code. 

Apache returns a 302 (temporary redirect). However, this particular case 
is always a 301 (permanent redirect). I don't think this actually affects 
any exiting cache-rs, but on my reading of the spec, it ought to not work 
(for 302, clients must use the original URI for future requests; 
generating relative URLs could fall under this heading).
