 // information for ftp. Provides lookup, insertion, and deletion of entries.
 // The parameter for doing lookups, insertions, and deletions is a GURL of the
 // server's address (not a full URL with path, since FTP auth isn't per path).
 // For example:
 //   GURL("ftp://myserver") -- OK (implied port of 21)
 //   GURL("ftp://myserver:21") -- OK
 //   GURL("ftp://myserver/PATH") -- WRONG, paths not allowed
