    // 1. At present our PAC code does not yet handle multiple PACs on multiple networks
    //    until something like https://android-review.googlesource.com/#/c/115180/ lands.
    //    Network.openConnection() will ignore network-specific PACs and instead fetch
    //    using NO_PROXY.  If a PAC is in place, the only fetch we know will succeed with
    //    NO_PROXY is the fetch of the PAC itself.
    // 2. To proxy the generate_204 fetch through a PAC would require a number of things
    //    happen before the fetch can commence, namely:
    //        a) the PAC script be fetched
    //        b) a PAC script resolver service be fired up and resolve the captive portal
    //           server.
    //    Network validation could be delayed until these prerequisities are satisifed or
    //    could simply be left to race them.  Neither is an optimal solution.
