Dear All, I using 2.6.Stable.4 squid on fedora 6 (planning to switch to fedora 9 (whenever release)) with one internet source. But due to non reliability of this source we have to hire high cost another reliable net connection (DSL). Now I want from squid to use the source one for regular use, but whenever source one is not available switch over to source two, and when again net is available from source one, switch back to source one. I don't know is that possible or not, if possible can anybody help me out for that. regards Arun
