-
- I see a problem coming here: how does an unreplicated document (say my
- own home page) mane a reference to such a replicated document? If I
- have a reference to the closest replica, a user far away who follows
- such a link will get pointed to the replica closest to *me*, not
- closest to her.
-
- Some possible solutions:
-
- - a translation scheme whereby clients "know" (e.g. from a local
- configuration file that may be updated automatically as mirror sites
- are added) that information at host X is identical to info at host Y
-
- - a magic string in hostnames that is translated dependent on the
- geographical position of the client (e.g.
- http://info-cern.closestmirror/...)
-
- - upon first contact with a server, it might respond with "please
- try the following mirror site which is closer to you" (this could be
- put in HTTP2 I suppose).
-
- This is a real problem with embedding location information in URLs...
