Maybe over simplified diagram, but on Tor project site, the overview shows multiple intermediate circuits, but only one exit.

I can see turning off Polipo as a test, but IF it turns out to be the problem, wouldn't that warrant opening a bug ticket? After all, it really shouldn't be sending addresses no longer valid (or allowing sites to access the old info) - yes? I'd rather not have to stop using Polipo completely. It has a lot of useful functions. I'm not aware of hidden cache in Polipo - others may know more - please chime in. Given it's only happened on one site (this was a free, completely open site), maybe it's a fluke. I really thought others would've seen a lot of same problem. Apparently not.

No ideas yet on what automated software that doesn't follow /robots.txt is forbidden, means? I tried again this time got on the site. Shut down Tor. Firefox - cleared cache. Restarted Fx Tor w/o Polipo or Torbutton enabled - accessed site OK. Shut all down again, as above, restarted FX, Tor w/ Polipo but Torbutton disabled - accessed site OK. Repeated shut down clearing cache, Restarted Fx, Tor, Polipo Torbutton - accessed site OK. Checked what IP address Tor exit node was using - diff, of course, from one shown above that was blocked. Seems site blocking access is related to _specific IP addresses_? There ARE no differences in setup of my Tor / Pol. / Torbutton today (when site access successful) as other day when blocked. One GOOD thing learned is by following all shutdown steps above, seemed to be able to stop same (old, incorrect) IP address being accessed / given to site. Other day, must've been something about sequence of shutdown / clearing cache that didn't clear the old IP address. UNKNOWN: When installed latest Vidalia bundle few days ago, did NOT check to see if Polipo was installed / running. My guess is it WAS, because today the reason I checked on Polipo is Fx would NOT connect w/o it. Common problem for many - get msg to effect, firefox is refusing to connect... blah, blah. Getting Polipo started fixes this prob immediately.

Re: IP address blocked on certain site
Why, after getting all new nodes especially new exit node IP address (I confirmed was a new address), would Tor send an old IP address (? from memory) to the site? Doesn't make sense. If Tor WAS sending an old address (to any site) after getting new exit address, something's really wrong. Doubt that's the case. You seem to have the misconception that Tor only uses one circuit at any given time, and that you can determine what IP address a server will think you are coming from by checking with a website. You can easily choose the same exits node after restarting Firefox, and I believe even after creating a new set of circuits with the Use a New Identity button in Vidalia. Tor builds several circuits that you can use at any given time. I think three is default... You can try to check your IP address with a website, but you can choose a different circuit to check than the one you actually choose to hit your desired website. The IP address check would show the IP address of the exit node for one circuit, while it's possible that you could be hitting the website you want to use through the same exit node (of a different circuit) again and again. If you are running Vidalia, click the View the Network button. You should see a list of the circuits Tor has built. Keep that window open while you surf, and you can see which circuits Tor is using. To force Tor to use a particular exit node of your choosing, first add 'AllowDotExit 1' to your torrc. Then you will be able to make requests using the .exit notation below: https://gitweb.torproject.org/tor.git?a=blob_plain;hb=HEAD;f=doc/spec/address-spec.txt SYNTAX: [hostname].[name-or-digest].exit [name-or-digest].exit For example: www.example.com.exampletornode.exit *** To unsubscribe, send an e-mail to majord...@torproject.org with unsubscribe or-talkin the body. http://archives.seul.org/or/talk/

If it's some hidden cache issue with Polipo, the issue would disappear then, no? Also he mentions opening a new tab, but never says he cleared the Firefox cache; could Firefox itself simply be fishing the page up from memory?

The 2nd option of Torbutton under PrefsSecurityCache, Block disk and memory cache access during Tor, may be the answer. see http://kb.mozillazine.org/Browser.cache.memory.enable Don't know what would have to do to clear mem cache from Fx activity - shut down computer?

Everything else you mentioned points to you using Firefox and Tor properly, I'd try either skipping Polipo (really only a testing solution, as by not using Torbutton, you lose all the other goodies it gives you (beyond simple SOCKS configuration), and would have to change Firefox's network config every time you wanted to use or stop using Tor). If it's indeed a Polipo problem and that fixes it, Geoff's solution seems like it would make a rather nice permanent solution for you. You could skip right to that if it sounds easier than screwing around with Firefox's network configuration.

Using latest stable Vidalia / Tor bundle for Win (Vista x64). Never really had this prob before installing latest ver, but could be coincidence. When using Tor/ Torbutton, only one site gave message (to the effect) the IP address you're using has been determined to be abusing this site ? / server ?. Access denied. Then it showed the full IP address. I could never get that site to stop showing that same, blocked address, no matter what I did. Tried closing the tab in Firefox. Then tried closing Tor Firefox, restarting. Same msg from site, w/ same IP address shown. Also, tried refreshing the Tor network, so all new nodes. Made no diff. After doing the above ( site still showing old IP address when I opened a new browser tab, then tried site again) I checked my ACTUAL current exit IP address by going to a Tor check site. As I figured, it showed a diff IP address than the blocked site was still showing, at the very same time as I checked at Tor check site. Somehow that old IP address was being stored somewhere, even though it was no longer the exit address being used in Tor network. How / why did the site keep showing the old address after doing all those steps? Is there an easier way to deal w/ this problem than the many steps I took?
