To really prove anything, you'd have to watch the server side as well, without that you can still make assumptions, though. If you enable connection debugging in Privoxy, you can tell from the log messages whether or not the problem happened while reusing a connections. If it only happens while reusing a connection it likely is a Privoxy problem. Otherwise it most likely isn't. If the problem goes away after disabling the keep-alive-timeout directive, and reappears right after enabling it again, that would indicate a Privoxy problem as well. If you report a problem for Privoxy 3.0.12, the first response will be Please try to reproduce it with 3.0.14 beta, so you probably want to upgrade before looking into this.

frequent empty/closed connections
With the last few versions of tor (I'm running 0.2.1.17-rc at present), I've been getting a *lot* of the following messages in firefox. Empty server or forwarder response. The connection has been closed but Privoxy didn't receive any data. In other words, instead of a web page, privoxy returns a page that is blank except for the two lines of text shown above, which appear at the top of the blank page. This is with privoxy 3.0.12. Usually, hitting refresh will get the proper page, but sometimes it takes doing that a couple of times. Does anyone else get these, too? I suspect that the problem may be in privoxy, rather than tor, but haven't yet figured out a test for that hypothesis. Any ideas? Thanks in advance for any information or suggestions about this problem. Scott Bennett, Comm.
