106237 - Mozilla unable to connect to IPv4-only server running on IPv4 and IPv6-enabled host

Status: VERIFIED DUPLICATE of bug 86917

(Core :: Networking, defect)

Description

[Russell King]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i586; en-US; rv:0.9.5) Gecko/20011012
BuildID:    2001101202

Client and server Linux kernels running IPv4 and IPv6 networking stacks, and DNS
for the server contains both IPv4 and IPv6 addresses for the servers name. 
(please note that this setup is currently behind a firewall).

The server is running Apache, built only for IPv4 support.  Attempting to access
the server using mozilla from the client results in "connection refused".

Note that `lynx' is able to connect from the same client successfully - it tries
an IPv6 connection, receives "connection refused", and proceeds to try the IPv4
connection.

Reproducible: Always
Steps to Reproduce:
1.Setup a Linux server running both IPv6 and IPv4 protocol stacks, with apache
only supporting IPv4.
2.Setup a Linux client running Mozilla.
3.Setup the DNS such that the server address has both IPv6 and IPv4 addresses
listed.
4.Attempt to access the server with mozilla.

Actual Results:  mozilla only tries to contact the IPv6 address when both an
IPv6 and IPv4 addresses are available.

Expected Results:  Mozilla should try all addresses supplied for a host name.
