No. Squid is an HTTP proxy and HTTP cache.

It can retrieve FTP, Gopher, Wais etc and convert them to HTTP for
caching when those protocols are requested via HTTP requests.

CIFS is a filesystem. I find it hard to see how one could request a
filesystem object on a remote machine via HTTP without involving a web
server of some kind.

The file:// protocol tag used by browsers is explicitly restricted to
the local machine file system and not sent to external proxies.

Additionaly, I found after your earlier post that CIFS is a part of
NetBIOS. Which is obsoleted now by Microsoft.
