Sometimes I am someone else October 25, 2006 6:15 AM   Subscribe

For a moment, I was logged on as another user (darthduckie ? sp) It happened on AskMe, but when I came here, I was lobstah again. I didn't try to post as that user, so I'm not sure how deeply I was logged in. Does this happen much?

Woah.

Woah was my reaction too. a little more info:

For the past few days, I have occasionally found myself logged out as I navigated to another page on the site. I would try to login again, but it wouldn't allow me, as if I had used a wrong password. If I navigated back, I would still be logged on, or, if I left the site entirely, and then returned, I would be automatically logged on.

Another data point: I've had the same thing happening -- being apparently logged out as I navigate to another page of the site (I'm clued in by the presence of ads), then when I moved to another page, being logged in. Also, once when I noticed there were ads on the page, I refreshed, and appeared to be logged in after the refresh.

I have not noticed myself logged on as another user, though.

Someone might as well ask (obvious as it is): public/shared terminal? Any possibility that darthduckie used the computer sometime in the past?

We've seen this happen a few times recently, mostly with people who are using Google Accelerator or whatever it's called. Are you guys using that? You won't be able to post as another user or edit their information, even if you do seemto be logged in as them.

Are any of you connecting through a proxy server?

Well, sometimes you don't even know if you are. Your ISP might have an invisible proxy. If you're at a university, you might connect through one. If you're on a wireless link, you might be going through a proxy.

The point is, I've had proxies fuck up in the past, and confuse me for another metafilter user who was connecting to the site through the same proxy. I appeared as someone who I happen to know was at the same university as me, and we figured it was the proxy messing us around. Caching something it shouldn't. Could that be the answer?

(Yeah, Google Accelerator counts as a proxy server, as far as I know.)

This happens to me from time to time from the office. It is always the same other MeFite username too.

It happens to me maybe once a month.

100% of the time reloading the page fixes it.

Ah, yes...It seems my lovely wife has indeed, added Google Accelerator to my bag of tricks. I will attend to her accordingly :P
posted by lobstah at 6:54 AM on October 25, 2006


You are seeing copies of the page downloaded by another user on your proxy server (Google Accelerator) but if you try and post, it will pull up your personal cookie details and be fine.

I can't think of a simple fix aside from removing that line of text on comment pages.

darthduckie here...I am using Google accelerator too, so that pretty much explains that.
posted by DarthDuckie at 7:25 AM on October 25, 2006

*cues omnious music and moody lighting*

So, yet another reason to avoid Google's accelerator (and unrelated, toolbar).

I prefer my data unsullied by you mortals. When I send an HTTP request, it and it's response had better be pure. Goddamn soil commies.

Of course, I did just utilize the Coral Cache network. To propagate a link to filthy commies.

I'm such a contradiction.

this is crazy interesting -- is there any way to explain that to the unwashed lowtech masses? because I'd love to understand how that happens, in my ignorance I thought it was impossible

Yeah I think so. Google has a service for people who want to access pages on the web faster. Instead of going to the original server to get new copies of the pages, Google will send you the most recent version of the page they have. So usually when you load a MetaFilter page, you are going all the way to the MetaFilter machine to get a copy of the page. If you use Google's service, you only go as far as Google which has super fast pipes and can often serve you the page faster than the MetaFilter machine. Google keeps fairly current copies of lots and lots of web pages, apparently. You'll really notice a speed improvement if you are trying to hit pages on servers with high load, or pages that don't change often.

The downside to this, with pages that change rapidly is that you may be looking at a page that is minutes older that the page that lives on the MetaFilter server. The other downside is that on pages like MetaFilter pages, where there is text identifying who the person is who loaded the page last in the header, Google sending you "their" copy of a page is actually sending you, in this case, darthduckie's copy, complete with header that says "hi darthduckie" or whatever. Your own computer still knows that you are you, based on your cookie, but the page you see has the raw HTML of someone else's page. This seems to only happen if you and the other MeFite are using the same Google server, though I'm not sure what that means exactly.

Does that make sense?

You can prevent that from happening by making metafilter uncacheable, but that would kind of throw the baby out with the bathwater.

You should definitely make profile pages uncacheable, though, if you haven't already.

lobstah: no joke, the same thing has happened to me a couple times and it is always under your name. I never tried posting either (although the nasty thought ran through my mind that I could post something outrageously offensive and start a huge flame war and watch as you tried to convince people it wasn't you, but it was only a passing reverie).

Here is the bug, noticed over a year ago. Apparently I need to change the cache headers or something. Every problem I have with Google is always made to be my fault.
posted by mathowie (staff) at 10:30 AM on October 25, 2006


This also happened once with someone I knew who worked at Microsoft. In large companies, everyone goes through the same proxy server and some of them do caching just as jessamyn described above.

That means she got a page that had been recently served to another user, who also happened to work at Microsoft.

for a moment i was sure mathowie was implementing the random sockpuppet assignment which was once suggested...
posted by quonsar at 10:44 AM on October 25, 2006


Ok, I added:

<CFHEADER NAME="Cache-Control" VALUE="private">

to the comment pages. I think that'll keep google from caching the login info.

Google Crossloginator!

It would be a great April Fool's prank if Matt switched everyone's usernames around (without fucking up their accounts forever or really allowing new posts to wind up on the other person's account).

This happens to me at work, where there is a proxy server and several other mefites. It's a bit disconcerting sometimes, because some of them have crazy big fonts and wild white backgrounds, but as has been said, I cannot post as or edit the profile of the other users. No Google product involved in my case.

Postscript to my prior post. Yes, I am using Google Web Accelerator. Never crossed my mind that that would be the problem.

You joke. But back when I first joined there was a strange interaction between the computer system where I work and Metafilter, such that if I switched between various workstations I would find myself logged in as mathowie. Of course, I was too damn boring & responsible to do anything other than report this to Matt.

I can't help but think of "Mother", off of The Police's Synchronicity:

Every problem I have with Google
Is always made to be my fault
Every problem I have with Google

All my bughunt expeditions
Always come crashing to a halt
Every problem I have with Google

Oh Google
