I know for HTTP object they have a Vary: and ETag: header which also
needs to match exactly on PURGE. Squid generates the HTTP headers for
FTP objects since they come from the FTP server without any. I don't
know offhand what squid adds that may prevent the PURGE. But its
something else to look into anyway.
