I need to hide my ip from time to time. In Vidalia, I click on "New Identity". Ihen I check http://myip.ozymo.com/ to see if my IP address has changed. But, no, it hasn't.

Why is that? And how can this be fixed?

I tried waiting till the button gets re-enabled to make sure that its done processing the command, but still the IP address is the same. In Fiddler each request is tracked, so it's not a cached response. It's re-requested, but simply does not change.

Fiddler though does show one thing interesting. Here is the raw response of many of the requests:

HTTP/1.1 200 OK
Content-Length: 13
Date: Mon, 23 May 2011 12:02:57 GMT
Server: Apache
X-Powered-By: PHP/5.2.14
Content-Type: text/html; charset=UTF-8
Age: 1
Connection: keep-alive
**Warning: 110 localhost:8118 Object is stale**
26.32.120.106

What is this warning? And is this the cause?
