[Sderby] squid proxy servers?

[Graeme Phillipson]

Hello All,
I've not posted to this list before, so I suppose I should introduce myself.
I use linux at work (www.codamotion.com), but as a programmer, not a system
adminisrator. However I get roped into that all the time.
We've been struggling getting a BT openworld satalite connection to work
(we're in a little village, no adsl, and ntl won't sell to bisnesses here).
It says it only supports 4 computers, and it would appear they *really* mean
it. I thought maybe it would only be for support purposes, but if you make
more than 4 simutaions connections the speed of all of them drops to around
0.3Kbs.
I'm wondering if it would be possible to configure squid to forward requests
differently depending on size, small requests would go over our ISDN line,
and big (say <500KB) would get forwarded to the proxy box that BT have
provided. Has anyone tried to do anything like that before?
Any help would be appreciated.
Thanks,
Graeme Phillipson.
