Confused over FTP support via Squid

From: Tony Singleton

     Hello,

         What sort of FTP support does Squid actually give, what I mean is does
 it actually uses ports 21 and 20 for the control and data between itself and
 the client (browser/ command line ftp), and on to the ftp server. How can this
 be when the host running squid may itself have a ftp server deamon running?

   +----------------+ control +-------+ +---------+
   º º--------->21 º------->21 º
   º Client Browser º º SQUID º º FIREWALLº
   ºFTP command lineº º º º FTP º
   º º<-------->20 º<------>20 SERVER º
   +----------------+ data +-------+ +---------+

    Or perhaps Squid is not actually doing FTP at all but just using the HTTP
 PUT and GET methods across the normal HTTP port (say 80 or 8080), to perform a
 FTP like ability (In which case command FTP will not be possible), so
 limiting FTP like access via a Web server.

          Thanks in advance for any replys.
