i fond a strange behavior in some case, sometimes the IP is "::1"
it looks like this happens special if pages are very fast reloaded
i have no idea what could cause this, and no idea how it can be fixed, and i don't now if this happens only offline on XAMPP or online on the server too.
(i simply found the "::1" in a log)
but maybe IP="::1" should be handled in some way?, specially for possible security reasons on the server (ip checks, DoS attacks, or what ever...?)
