[For the first of those, if you go through the stuff in nsHttpConnectionMgr until you get to the call to nsHttpConnection::Activate. This calls CreateTransport, whcih calls into the socket transport service, etc. You'd need to trace into that to find the NSPR code that actually does the socket-opening, which is probably different on different OSes. For the second, nsHttpConnectionMgr::AddTransaction (called when setting up the transaction) calls PostEvent, which dispatches the event to call OnMsgNewTransaction to the socket thread. So there are basically two threads in play here, as I understand: the UI thread, where the asyncOpen happens, and the socket thread, where the socket access happens. I think there is also a thread pool that comes into play later (from the stream transport service), but I'm not sure how that fits into the setup, to be honest. --[[User:Bzbarsky|Bzbarsky]] 09:00, 9 July 2008 (PDT)] | |||
