squid's behavior when using wget to ftp a site?

hello,

SCENARIO:
When ftp'ing (mirror'ing) a site using wget thru squid, wget/squid
closes the connection after fetching a file then reconnecting again.

QUESTIONS:
Is squid the one that closes the connection after fetching one file? or
wget? if the former, is this squid's regular behavior? and how to
reconfigure it?

Or is this completely a wget behavior and has nothing to do with squid?

PROBLEM:
This behavior of wget/squid connecting and then reconnecting again
actually takes *more* time than the actual fetching of the files.

Any suggestions?

please cc: to my address
