#define ENOATTR ENODATA

This file is part of the CernVM File System.

CernVM-FS is a FUSE module which implements an HTTP read-only filesystem. The original idea is based on GROW-FS.

CernVM-FS shows a remote HTTP directory as local file system. The client sees all available files. On first access, a file is downloaded and cached locally. All downloaded pieces are verified by a cryptographic content hash.

To do so, a directory hive has to be transformed into a CVMFS2 "repository". This can be done by the CernVM-FS server tools.

This preparation of directories is transparent to web servers and web proxies. They just serve static content, i.e. arbitrary files. Any HTTP server should do the job. We use Apache + Squid. Serving files from the memory of a web proxy brings a significant performance improvement.instead of including attr/xattr.h
