Assume there are nice webpages on remote hosts we want to bring into our namespace. For FTP servers we would use the mirror program which actually maintains an explicit up-to-date copy of the remote data on the local machine. For a webserver we could use the program webcopy which acts similar via HTTP. But both techniques have one major drawback: The local copy is always just as up-to-date as often we run the program. It would be much better if the mirror is not a static one we have to establish explicitly. Instead we want a dynamic mirror with data which gets updated automatically when there is need (updated data on the remote host).
Solution:
To provide this feature we map the remote webpage or even the complete remote webarea to our namespace by the use of the Proxy Throughput feature (flag [P]):
