 Observe that the command ``http_xsltproc.sh -F`` forces a fresh SAML metadata file. If the server responds with ``304 Not Modified``, the process terminates without updating the resource file.

 Observe the commands ``http_xsltproc.sh -F`` and ``http_xsltproc.sh -C``. The former forces a fresh SAML metadata file as in the previous example; the latter goes directly to cache. If file is not in the cache (which is highly unlikely), the process terminates without updating any resource files.
