Hello, I'm behind a proxy server at my college, that requires authentication, but I need use some programs that does not support proxy authentication (e.g. matlab) Someone told me that I can use SQUID as a second proxy and this should be authenticated in such form that network requests submitted from the machine do not require authentication. But, really I don't have very clear ideas for how to use SQUID, or another tool... Any help would be grateful!! Alex. S. PS. It is for research purposes, for my M.Sc. Thesis PS2 Is urgent, indeed PS3. Thanks anyway...
