DumpFilter

The task of the DumpFilter is to dump the request and response in a file. The DumpFilter (as well as the CacheFilter) creates directories whose permissions are set to 0772 so that anyone may dump into the directory, but only users of the same group have read access. Dumping of all requests without any limitation will lead to problems in production environments.

DumpFilter should therefore only be used for trouble shooting and integration tasks!
