Cache servers differ from regular servers in that they do not produce warnings and are not removed from the server pool for "soft errors" (i.e. the server was reachable, but the download failed) and they are not used for databases. If a host is used for both a cache server and a regular server, it may still be removed from the server pool for soft errors that occur when used as cache server and removal from the server pool for soft errors will not affect future attempted use as a cache server.
