That resource declaration says: "the target node should have a file
/usr/local/temp, with mode 777 (octal), whose content exactly matches the
content currently available from URL puppet:///files/temp (which refers to
the built-in file server on the master that served the catalog)." The
Puppet agent will check on every run whether the declaration is already
satisfied, and will update the target file as necessary to make it comply.
The agent will *not* download the file again if it already matches, but it
will do if the file has changed *on either side*.

By default, Puppet checks for matching file content by computing and
comparing md5 checksums (so specifying that explicitly is unnecessary).
The client computes the one for its local file, and the master computes and
reports the one for the remote file.

There are several ways to modulate Puppet's behavior here by changing or
adding to your declaration, but to recommend anything we need to be sure we
know what your real requirements are. The behavior you say you want sounds
very much like what Puppet does by default, so if it's really behaving
differently then there must be something you're not telling us.
