158511 - DNS: seems to cache results

Status: VERIFIED DUPLICATE of bug 162871

Description

[mar_garina]

Looks like mozilla caches the dns (or any other hostname-resolution method)
results- If I'm updating an A record in my local dns, mozilla will still use the
old value until I'll restart it.
I don't see a reason for internal caching of hosts/IPs anyway- I think that's
the job of the os (i.e. many unices are running nscd), and besides, hostname
resolution is a quite fast operation usually.

From comment #2 for bug 109313 (linux specific):

> It's really glibc that's caching /etc/resolv.conf so it's sort of a 
> system issue. There are ways around it but they're very non-standard.

DNS servers are not "cached", they just kind of get stuck in most Linux builds.
(To me cache implies we did this on purpose for some performance reason).

Bug 162871 is the current DNS cache implementation discussion.

reporter: Please look at it and VERIFY if the problem descriptions are duplicates.

VERIFIED/dupe.

This is all changing in 1.6a's DNS rewrite anyhow.
