squid + http-gw + ftp-gw

H.,

I have a squid proxy with a http-gw(TIS) as parent, in the configuration
file I put
cache_peer 192.168.67.227 parent 6363 0 default no-query
but I need that squid connect to http-gw for http urls and ftp-gw for
ftp urls.

With this configuration all ftp request go to http-gw(port 6363). I know
that squid perform http request by the client side and ftp & http
request by the server side, but I don't know how tell him that
192.168.67.227 is a proxy server for http and ftp and that redirect at
each port of 192.168.67.227 the correspondent protocol.

clients ---> squid-proxy ---------> http-gw(port 6363) --->|
                             | | Outside
world
                             |----> ftp-gw(ports 20,21)--->|

Regards,

J.M. Fandiño
