Query: A network file system over HTTP: remote access and modification of files
  and "files"   The goal of the present HTTPFS project is to enable access to remote files,
directories, and other containers through an HTTP pipe. HTTPFS system permits
retrieval, creation and modification of these resources as if they were regular
files and directories on a local filesystem. The remote host can be any UNIX or
Win9x/WinNT box that is capable of running a Perl CGI script and accessible
either directly or via a web proxy or a gateway. HTTPFS runs entirely in user
space.
  The current implementation fully supports reading as well as creating,
writing, appending, and truncating of files on a remote HTTP host. HTTPFS
provides an isolation level for concurrent file access stronger than the one
mandated by POSIX file system semantics, closer to that of AFS. Both an API
with familiar open(), read(), write(), close(), etc. calls, and an interactive
interface, via the popular Midnight Commander file browser, are provided.
