Yes, my issue was as followed: I used proxies to connect to a site, thus
hiding my IP. Without noticing, since I was using Firefox, one of the
windows (open in a new window) was still open when I closed the proxy
program and changed the browser to "directly connect". I did not
connect the the site again, but simply closed the browser window for
that site. I was wondering, since there was no connection to the site,
and the site does not automatically refresh, if the site could grab my
IP. I had not heard of the keep alive technique, but it would appear,
that because the specific connection was broken when the proxy chain was
closed, that the site could not have grabbed my IP. I take it this is
correct and thank you, once again, for your informative responses.
Incidenatlly, in FF options I can not see an option not to use keep
alive technique.
