WFM, I see no difference between Moz 1.7b, FF 0.8 or IE 5.0 on WinNT4.

Comment 2

[Christian Weyland]

this seems like a pipelining issue. site is completely broken in mozilla with
pipelining enabled but properly working when disabled.

however, there seem to be no problems with current firefox (regardless of the
pipelining-settings).

confirming pipelining breaks the site (FF 20040319 Win2k), perhaps it's worth
adding Netscape Enterprise 6.0 to the black list ?

Umm... using 1.7b on WinXP the site looks fine even with pipelining enabled.
Yes, Cache cleared and all.

Comment 5

[Olivier Cahagne]

mmm wfm too using FF 20040401 on Win2k (tried both pipelined and non-pipelined)

Comment 6

[Andreas Kunz]

Then the issue is more difficult to trace:
I don't think there were lots of network changes between 20040319 and now
(Olivier once saw it, now not) and I also don't think FF does differ from
Seamonkey network-wise (Christian saw it with SM, but not with FF).

Comment 7

[Christian Weyland]

I'm now seeing this also in FF (20040408) on Win2k. However, it is not always
reproducable and happens most often after reloading the page (which previously
displayed correctly).

Anyway, I don't see it anymore with pipelining disabled.

[Darin Fisher]

confirming.  problem is reproducible in FF 20040315 linux trunk.  pipelining
specific bugs are low priority right now.

www.qwestwireless.com redirects to qwest.com, which is running Apache, and I see no problems with pipelining enabled, so this appears to be resolved.

http://toolbar.netcraft.com/site_report?url=http://www.qwest.com

According to the following page, Netscape Enterprise 6.0 is down to ~6000 servers (0.01%)

http://www.securityspace.com/s_survey/server_graph.html?type=http&domaindir=&month=201007&serv1=TmV0c2NhcGUtRW50ZXJwcmlzZS82LjA=

Many of the NES6.0 servers I found were redirects to servers running Sun-ONE-Web-Server/6.1+, Apache, etc.

I don't see any problem with pipelining with these NES6.0 websites:

https://argus.uwf.edu/, http://fcps.edu/, http://www.usps.com/, http://excite.co.jp/, http://cigna.com/, http://www.sunrisemedical.co.uk/, https://www.divinvest.com/, http://labavn.org/, http://tm.hilton.com/, http://www.regenthotels.com/, http://lpse.jatengprov.go.id/, http://www.sprintpcs.com/pages/dataPlanEducation.html, http://www.cengage.co.uk/
http://www.dialog.com/, http://www.scotiabank.com/, http://www.edwardjones.com/

However watching the following NES6.0 websites with Firebug shows 'Aborted' requests which are refetched OK; I'm not sure what that means.

http://cibil.com/, http://www.caixalaietana.cat/, http://cuba.cu/
http://tmxmoney.com/, http://www.topamax.com/, http://www.nova.edu/, http://www.eudora.com/, http://www.tmx.com/, http://mtnlmumbai.in/, http://opel.de/

These NES6.0 websites perform very badly when pipelining is enabled, with only part of the page contents loaded initially, and the rest of the content arriving after a ~1-2 minutes delay.(probably a separate bug)

http://mibcn.com/
http://www.johnhancock.com/

None of these show the originally reported bug.

John, I think C#10 is really interesting, thanks. At the very least it shows that NSES6 really doesn't benefit from pipelining (it closes the connection - that's where those aborts are coming from), so the rare versions of it on the internet could safely go into a blacklist without a downside.
