Subject: bug#526: Emacs 22, url package, problems with cache

The url-automatic-caching variable is nil by default, so cache is not written (even the cache directory is not created).  However, if I manually provide "If-Modified-Since" header in HTTP request and the server responds with "Not Modified 304", the cache file is expected to exists and is accessed -- which leads to error.

Possible solution -- before accessing the cache file, check whether it exists (url-is-cached).
Alternatively, do not expect a cache to exist if url-automatic-caching is set to nil.
