583634 - Name-resolution broken for private domains

Status: VERIFIED DUPLICATE of bug 66183

(Firefox :: General, defect)

Description

[Mikhail T.]

My home network has a domain of its own (narawntapu). Firefox was cool with it until recently...

Nowadays (using 3.6.8 now, not sure, when exactly the problem started) clicking on the same bookmark for a local web-server (video camera) like: http://cam.narawntapu:84/ attempts to show http://www.cam.narawntapu:84/ (note the bogus www. getting inserted), which does not exist, of course.

Could this "helpful" non-sense, please, be ended? It was bad enough to stop Verizon from redirecting mistyped domains to their own web-site. No my own browser is trying to be smarter than me?

I thought, perhaps, this is Vista's DNS misbehaving, but running nslookup on "DOS" command line resolves the name to its IP just fine.

Thanks!

The additional www part in the error message doesn't matter and it's another bug.
I don't understand your nonsense part and it also doesn't belong into a bug report.

I can't reproduce your issue on SM trunk, FF4.0b2, FF3.6.8 on win7, win2003 and Ubuntu

I think that this should be merge with 66183

There is no www in the error message. www is in the URL it is trying to access. I will type http://cam.narrawntapu/ and it will automatically switch that to http://www.cam.narrawntapu/

Try typing http://foo/ into the URL. You'll end up at http://www.foo.com/

If "foo" is not a defined host on your machine, this is an expected behavior. Please read https://www.mozilla.org/docs/end-user/domain-guessing.html

You might want to clarify the original bugreport, but the foo-> www.foo.com is not a bug.

Ok, I thought, it is a manifestation of the same thing... What I am typing, however, is an existing host here -- nslookup would resolve it...

Maybe, it is some glitch in Vista's name-resolution, that causes it to return a host-not-found, which then causes Firefox to try again with the www-prefix.

But, at any rate, if the "guessed" hostname does not exist either, the originally-requested hostname should be put back into the (failed) URL, IMO.

Yeah, that's bug 66183.

I somehow missed the response.
bug 66183 is what I meant with the www part in the error message.
That www is tried is the domain guessing and expected.

The can't reproduce part in my comment means that Gecko can resolve a private domain on my system.
