proxy caching of error messages

[Chuck Murcko <ch...@topsail.org>]

Is there any problem with the proxy not caching 40o series errors? This
will probably clear up some complaints about this behavior in the
current proxy code. Any others that definitely should not be cached?
Currently the proxy uses Ben's original strategy for caching:

/* 
 * what responses should we not cache?
 * Unknown status responses and those known to be uncacheable
 * 304 response when we have no valid cache file, or
 * 200 response from HTTP/1.0 and up without a Last-Modified header, or
 * HEAD requests, or
 * requests with an Authorization header, or
 * protocol requests nocache (e.g. ftp with user/password)
 */
