Re: Logged in status does not persist (http://perlmonks.org/ + no "third party" cookie)

After a tcpdump, I saw that after perlmonks.org has been resolved to an IP address, that (IP address) gets resolved to perlmonks.pair.com host name. Hence the cookie problem with using "Accept cookies only from the site I visit" option but not with "Accept cookies".

Now, if log in on perlmonks.pair.com AND choose "Accept cookies only from the site I visit" option, I have no more ephemerally logged in problem.

Ah, so the problem is that reverse DNS is broken. I'll have to file a ticket with pair.com and perhaps a request with the host of our DNS config (I'm not sure the host of our DNS can even do anything regarding reverse DNS). Thanks. You should probably file a bug against your browser, since rejecting cookies based on reverse DNS is something that one should at least be able to disable (and that probably shouldn't be enabled by default). My guess is that it is some attempt at "security" but it seems rather pointless (as well as disruptive). - tye	[reply]

Ah yes, "reverse DNS" is the phrase. I just checked in Firefox 12.0, where turning off "Accept third-party cookies" while "Accept[ing] cookies from sites" did not cause the problem observed in Opera.	[reply]
