User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.1) Gecko/20020826
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.1) Gecko/20020826

When trying to connect to www.news.com, the status bar stays on "Transferring
data from www.news.com" and nothing is displayed (it should redirect to
news.com.com).

Query :
GET http://www.news.com/ HTTP/1.1
[headers]

Answer :
HTTP/1.0 301 Moved Permanently
[headers]

When trying to connect to news.com.com, nothing is displayed. DNS resolution is
happening (CNAME www.com.com A xxx A xxx A xxx), but Mozilla does not connect to
the web server (no TCP packet are seen by ethereal after the DNS resolution).

Connection to www.com.com works.

Reproducible: Always

Steps to Reproduce:
1. connect to news.com.com
2. wait forever



We use a squid proxy with a .pac configuration.

WFM - 1.1 release - WinXP

By the way, I do not use any proxy.

ISP problem?

Comment 3

[JF Bustarret]

No ISP problem : it works with IE.

It's a major bug, because I am FORCED to use IE against my will...

Comment 4

[Jo Hermans]

Worksforme with Mozilla 1.1 release on Windows NT
Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.1) Gecko/20020826

Reporter, can you try again with HTTP-pipelining off, if that was enabled ?

Comment 5

[Mitch]

Works for me on Solaris cvs 20020823. I'm behind a squid proxy.

Comment 6

[JF Bustarret]

Did some tests before lunch... Works the first time, and not the
second/third/... time (with or without pipelining).

Did some tests after lunch... Works every time.

I'll do some more tests...

The fully qualified domain name doesn't look correct.  There is double ".com". 
I have no knowledge that there is such a domain ".com" within another ".com".

Comment 8

[JF Bustarret]

com.com is a real domain, and is owned by CNET.

I still have the problem.

Apparently :
- I can connect to news.com.com just after starting Mozilla,
- After a variable amount of time (30s up to at last 10 minutes), I can't
connect to news.com.com anymore.

Comment 9

[Sam J. Fleet]

Could Mozilla get confused by seeing the double ".com"??  Could Mozilla be lead
to believe that it is that and not the domain name, "com.com"?

Comment 10

[Darin Fisher]

when connecting via a proxy server, mozilla only resolves the hostname of the
proxy server.  it does not resolve the hostname of the site you're trying to
load... it leaves that up to the proxy server.

reporter: it'd be helpful if you could attach a packet trace to this bug report.
thx!

The keyword here is PAC, so if JF could post the PAC file as an attachment, that
would be good to look at.

Two things:

Please try news.com.com directly. My experience is that you will get the same
content.

If that works, then we have a possible re-direct problem. (if you could post the
complete headers of the 301, that would be great).

If not, then we have a likely PAC problem w/ the domain. If you nslookup the IP
address of news.com.com, and put it into the URL, you would probably find it
works, which would isolate the problem.

Comment 15

[JF Bustarret]

I can't connect to news.com.com through its IP adress, because CNET uses virtual
hosting and www.com.com is the default host. www.com.com or the IP address
always work (even when news.com.com does not work).

nslookup news.com.com :

Name :    www.com.com
Addresses:  206.16.0.140, 206.16.0.141, 206.16.0.142, 206.16.0.143
          206.16.0.145, 206.16.0.149, 206.16.0.134, 206.16.0.187
Aliases:  news.com.com

I tried this :

1. Switch to manual proxy config
2. Reboot PC
3. Launch Mozilla
4. Wait a few minutes (news.com.com always works just after launching Mozilla)
5. Type news.com.com => does not work
6. Type www.com.com => works (and works always)

*** Ethereal does not see anything for the news.com.com request ! ***

=> Looks like it's not a .pac problem, and not a redirect problem...

BTW, here are the HTTP headers of the redirect for http://www.news.com :

HTTP/1.0 301 Moved Permanently
Date: Tue, 27 Aug 2002 08:37:10 GMT

Changing title.

I have reproduced the problem.
- news.com works when the bookmark is not scheduled (Check location for updates
: 'Never')
- news.com stops working when bookmark is scheduled (after the first schedule ?)

Steps to reproduce :
1. Access www.news.com
2. Add bookmark
3. Display the bookmark's properties
4. Schedule : When (Every day), From (Midnight) to (11PM) Every (60) minutes
5. Notify : Change the bookmark's icon
6. Restart Mozilla
7. Wait 5 minutes
8. Click on the bookmark

I don't know why that is the case, but at least the cause is known. Before that
you had me very confused.

Comment 19

[Shailesh Mungikar]

I see the same problem with other web site www.theserverside.com. Same behavior.
Schedule the bookmark. Try loading the bookmark manually. It hangs showing
"Loading...". Turn off the scheduling. Restart Mozilla/Phoenix. Click on the
bookmark. The link works.

-> bookmarks

Comment 21

[Asa Dotzler [:asa]]

Is this still a problem with current (1.7 beta or newer) builds ?

Comment 22

[Asa Dotzler [:asa]]

I can't reproduce this with Mozilla 1.7 branch build 2004041608 on windows XP.
Does the bookmark actually have to change to show the update before the problem
arises or is just setting it to schedule enough to break it?

Comment 23

[JF Bustarret]

Tested it with Firefox.

It works...
