I had a very busy week trying to implement a feature and this week will be more of the same. Tomorrow morning I have a conference call at 9AM.
I curse the person at Netscape who invented proxy auto configuration. You can’t simply read & parse a .pac file – you need a javascript interpreter to do it properly. It would be a lot easier if I could use CFNetwork, but I wrote my own networking code which, among other things, implements much of HTTP 1.1 using BSD sockets. It always supported manual proxy setup, but not auto configuration.
